Are will still waiting for Q1 2015 for broadwell or has there been good news?

Haven't looked for a couple of months. Are we still waiting for Q1 for Broadwell mobile i7 or has there been some good news?

(the macrumours Feb article saying broadwell Q1 2015)

No news from Apple. But from what I've been reading in the tech news it would be a miracle to see Broadwell in Q3, small chance of Q4 and definitely by Q1 '15.

I plan on selling mine and upgrading (for Maxwell too of course) so I'm also pretty eager to hear any solid news... Will make for an unbelievable gaming system .

What will make broadwell better than haswell? I have a haswell in my MBPr.

Its the die shrink so lower power consumption (i.e higher performance per watt) and possibly 40% increase in graphics performance.

22nm 1st gen FINFET Haswell... Same Haswell architecture (new graphics core though) built on a 14nm 2nd gen FINFET process. You are looking at a 30% power reduction at least.
So for the same performance better battery life and improved integrated graphics.

Throw in Maxwell on TSMC's new 20nm process and you're looking at the 850M offering a 50% boost in performance with no extra heat output or power consumption. So a pretty worthwhile upgrade, at least for me.

The biggest difference for the 15" should be the system on a chip Quad Cores.
The dual cores made a big jump in power efficiency due to becoming SoC. The Quad Core Haswells didn't offer quite as much. Broadwell should bring down chipset power consumption of the 15" to the 13" MBA,MBP level. Which could give quite a boost in battery life.

Then there is 30% better power efficiency overall but that might not be the case for the first batches. Often this numbers refer to equal maturity not a fully mature 22nm to the new 14nm.
The GPU will mostly be better on the 13" purely from getting the Crystalwell memory treatment. EUs are only supposed to increase by 20% and who knows what the Gen8 architecture will deliver in efficiency gains per EU. They used to say 40% overall as their traget but I guess 20% at least and potentially it could be more than 40%.

I'm not waiting and I'm not buying either

I have a 2012 rMBP and its plenty powerful for my needs. Perhaps when 2016 rolls around I may change my mind but so far Broadwell doesn't offer anything to entices me.

Battery life is excellent already. GPU performance is nice, but buying a Macbook pro for GPU performance is not smart.

I probably wait till there is a new improved architecture (so probably Skylake / Cannonlake) or a new evolution of the Macbook Pro.

"We" is very broad of a group to apply to this refresh. I'm not waiting for Broadwell, I'm waiting to graduate, buy a new car and then I'll be buying whatever Mac suits my needs at that time. I don't care if it's Broadwell, Haswell or if I skip the well and cross the bridge, as long as it has what I'm looking for.

The more people shop with that in mind, the less waiting they'll spend and the more time they'll spend enjoying their new toys.

What about speed? Will Broadwell be faster? I can't imagine it being faster for day to day processes (opening notes, mail, calendar, numbers, etc) as Haswell is essentially instant opening on click.

A 2008 machine with SSD and enough RAM is fast enough for this. But Broadwell will be even more energy efficient (= longer battery life) and might offer some more performance for people whose day to day tasks are a bit more demanding. There is more than mail and numbers

If Broadwell rMBP shows major improvements besides battery life, I'll consider it but 2012-2013 rMBP users should wait for Skylake models (2015) because that processor will change almost everything.

Why not? The cost of my upgrade should be less than £300, not too sound arrogant but when we are talking about top end Retina Macbook Pro's it's not so bad. Plus I do really make use of the GPU and squeeze it for everything it's got.

No you won't notice any difference in those sorts of things, it's far more related to the SSD than the CPU in those cases. I'm not implying Haswell is slow or Broadwell will destroy it in benchmarks - it won't. It's a process node improvement which means less power consumption.

We don't know much about Skylake and I think it could be some time before we see it. Broadwell is now around a year behind schedule, it will be sometime before we see Skylake and I also feel CPU performance isn't something I have ever felt limited by with my rMBP. Skylake will be here in 2016.
