No, you could not. Why? Because most of what you have listed is either pure speculation or completely subjective.
1. An improvement is an improvement. For the significant future, CPU performance improvements will be incremental. Moreover, the 460 GPU is a significant improvement and this will be taken advantage of. By your logic, there has been no reason to upgrade over the respective predecessor for the past 5 years.
2. No, it's not.
3. Not a problem. There are faster solutions and has led to a more portable computer for mobile use.
4. This is an improvement, it's hilarious you've listed it otherwise.
5. You win. One small sacrifice.
6. New tech is always more expensive. Not a problem. If cost is the issue, the OP wouldn't even be considering the 2016 model. Otherwise, it's a non-issue. 7. No, there isn't.
"An improvement is an improvement" is true, but to the extent that I would want to purchase the 2016 model over the 2015 one is subjective, hence why I say that it is not a clear-cut decision to pick either models.
The processor speed is increased by +0.1. I'm not really going to point fingers at Apple, because at the end of the day, Intel is severely lacking in upping the performance of these processors.
Next, anything will be a significant improvement over the M370X, which was just a rebranded 2XX card, which in it of itself was awful. So taking a below-average card like the mobile version of the 460 is nice, but is not something that I would seriously consider in spending at least $2600 in.
On top of that, I'll include one of the QC issues I meant here. The 2011-2013 models of the MacBook Pro were known to have a lot of issues concerning their dGPU's. I'm only specifying these, because even though the 2010 and 2014-2015 models were also affected, Apple laughably only acknowledges these three years of computers. I had my computers (2012 and 2015) affected as well, and one of the clear symptoms was when the computer screen froze, and I could do nothing but force shut down the computer. Well, we're already seeing reports of these things happening with the MacBook Pro 15", specifically the ones with the 460 card:

Also, I'm sorry to say, but the battery life is shorter. But in terms of size and usage. The sizes of the batteries of the MacBook Pro's of the 13" and 15" variants are 74.9-watt-hour and 99.5-watt-hour respectively, from 2015. For 2016? 49.2-watt-hour and 79-watt-hour. That's a decrease of 34% and 20% respectively. That of course doesn't take into account the Skylake CPU's, which are more efficient, as well as the software-hardware integration. But how about the following reviews, which state the battery life is so-so compared to last year's?:

Let's talk about dongles and adapters now, because that's most of the complaints I have. Apple has a "vision" for the future. Well, professionals have a vision of keeping their jobs and doing the most effective that they can do
now.
Well, let's say I want a USB-C to the following: Lightning (To charge my own phone), Digital AV multiport adapter, and USB adapter. The total for these three cables will be $83.16 without tax. Ah, I forgot the SD card reader. Another $29. So over $100 in accessories that I need to buy right now. What a future, am I right?
I must have these four cables with me at all times. I like to hook my computer up to a monitor at work, as well as the one I have at home.
I will make the argument of, well what if I forget one of these cables one day to work? How will I show a presentation I have on my MacBook Pro in a conference? The only option then would be to embarrassingly send the file to my co-worker, and use his computer because it has an HDMI port that I can easily plug into. A counter argument will be made that, "Hey, just don't lose the adapters!" But unfortunately as humans, we are all prone to making mistakes. Can you imagine if I lose an adapter and I absolutely need one right away? I will need to run to the nearest Apple Store or Best Buy. Again, what a future.
It's also an added hilariousness that some USB-C adapters won't work at the same time with WiFi. Why? Well I've read that because any of these ports can charge the computer, a very minuscule amount of current ripple can occur over the connections, and because of this, it's evident that Apple failed to test peripherals properly. In other words, not only could Apple's own peripherals not work (Feel free to read the reviews on their own website), but it's not a far stretch that the ones on Amazon won't either.
Here's a demonstration of that:
Next, let's talk about MagSafe. A "small" sacrifice, you say? Hm. I can't count the number of times someone tripped over my laptop charger, whether it be at a library, a conference room, or another public place, and the charger simply plopped off the computer. Equating the term "small sacrifice" to my $2000-4000 computer being damaged doesn't really make sense to me, but okay.
In addition, let's talk about costs. Again, you'll have to see the "full" picture. In this case, what I wrote up up above, and on top of that, the costs. So let me spell that out: The battery life (Which is better on the 2015 models), the fact that I don't need to ever worry about dongles because the 2015 MacBook Pro's come with HDMI and SD card slots, as good of a screen as this year's, a less controversial keyboard, MagSafe, AND costs.
Funny how you never mention the QC issues, but hey, enjoy your new computer. I said in the beginning that it's okay if you want to purchase the new MacBook Pro. It is in my opinion that if you have anything older than the 2012 retina MacBook Pro, it is a worthy upgrade. But if you're trying to make a clear-cut argument that, "OF COURSE the 2016 model is better than the 2015," then no. I disagree, and I find it sad that people like you are trying to make it a much more black-and-white distinction than it already is, for people who are about to pay thousands of dollars for a device they will use for t
