I really hope Apple puts a quad core processor in the upcoming Haswel based rMBP 13. There is already a Ivy Bridge 32w quad core mobile processor, but i don't see why apple didnt choose to use that processor, or at least offer it as a upgrade.

Anyway,
for that question, i think we should see a refresh on or before WWDC2013
 
Anyone can agree that if you want to buy a macbook now for yourself and you don't really need it right now the right decision is to wait for haswell bump. I mean is already mid March.

Well, yes, If you really want to wait ~6 months. Personally I would go for cheapest / proper IB rMBP and then sell it right after Haswell launch. If switching will be worth it.

You may be few bucks short overall, but it really depends what are you doing with your MacBook. Browsing Facebook and reading mail may certainly wait, but any work related stuff that can be done faster on actual rMBP may pay off a lot more than the money lost on Haswell update.
 
I strongly disagree with the assertion that Haswell will translate to any noticeable difference for most users.

Where did I say most users? I said many users who are using MacBook Pros. I even mentioned for most users a low-spec MacBook Air is enough.

You can yawn, but for many of us who yes, use Macs for computationally intensive app development on the move, Haswell will give an immediate boost by simply recompiling the software. Mac laptops are hard to beat in terms of portability/speed, so many developers chose them for that reason as well as relatively good development tools and their Unix roots. There are few laptops where you can run OSX, Windows and Linux on virtual machines and support software for all three platforms. You cannot carry 16 Xeon cores with you. A MacBook Pro retina is as powerful as a 5-year old workstation in under 4.5 pounds.
 
With Haswell, what should the increase in battery life be for the rMBP?

It is one of the deciding factors about whether or not I should get the computer now or wait.
 
I would agree. They try to make them compact. I have seen others on this board joke about how some other notebooks come with power bricks. It doesn't have to charge the machine while running at maximum load, but either providing one that can sustain it at that as a standard option or even a cto or accessory. Right now there isn't anything. It also adds quite a few cycles while plugged in if you encounter this regularly. That too is extremely annoying.

Im not about charging while running, Im about using the battery to provide enough power to run it when at full load, that for me is something that I dont like it.

it should they have created a new sleeping state, people already commented on this.
