after much thought i have come to the following conclusion: BUY NOW
look no one knows when the MBP's are coming out. some say feb, some say march/april/may- its not 100% certain. the rumors are picking up a bit, but not as much thus a estimated prediction of marchish/april. (i assume that ipad = feb?)
but lets suppose (just
PRETENDokay!) that the Mac book pro comes out tomorrow (with all the other stuff , LP/SB, etc). what will you do? buy it or wait?
my guess is the first thing that comes to your mind is- BUY IT!! because "well i have been waiting for such a long time and its cool and amazing and i like it

" great so you buy it but since the new features were added, however, they jacked up the price by $100, not much but still $100. you go home open it and play around
20 days later, anand tech posts a review saying that its not as well expected, although the processors and graphics are good, this is something we experienced, that, etc.
what i am saying is, even though the update comes in say 3 months, you would have to wait another month or two (and sometimes more) to get the full review on it, and the ups/downs. why waste money on a product that is lower in comparison to the previous product? (im not saying the next gen will be worse, but once again pretend)
sure you might buy it and then have ot live with the failures, but still you want a better bang of your buck, right?
so this is why i say buy it now. the wait will be much less- delivery or pickup? rather than waiting for release than delivery or pickup... and you have other reviews on it.
so before apple does something crazy like change their HDD to SSD (the air type- i doubt it but who knows) and some other funny stuff, buy it now and not regret it. tech is gonna keep changing and either you loose money to stay on top of it or be satisfied with whats available.
sure apple may include lightpeak, but whats the use of lightpeak if you have to spend extra $ to get an adapter or have to wait for light peak compatible things to come out..,
yes, sandy bridge is amazing. i want SB too, (im stuck on getting a MBP 13 as others are too expensive) and im stuck with a C2D, far worse than a i5 or even SB, but face it, when SB comes out, intel will be devising a way to come out with another better chip that is much better and apple will implement that in its next update.
with the current gen. you are 100% positive that things can be upgraded from HDD to SSD, to taking out OD to putting in a second drive, etc.
so why wait and increase your desires and thirst for a new product you are un-aware of.
i mean it all comes back to you:
if you need it now, BUY IT, if you can wait- WAIT..
but the problem with that, is you dont know what you are waiting for.there are rumors saying that SB will be in MBP's, but who knows. everyone thought that i3 wouldve been in the MBP 13, but it wasnt.you are more familiar with the current model (if i am correct) than the new one, you know hte pros and cons of the current model but you dont know the pros and cons of hte next gen. what if the next gen is worser? what if the next gen looses battery life? what if... these questions should not be asked, but still think about them.
a lot of people say wait wait wait. ok wait- but wait for what. we have not a single idea what apple has in mind, how apple will come about including that in the next update, when the next update is, and what changes will there be.. we know nothing. the most important facts are kept hidden (part of apple marketing but still) . why go in blindly to something we are not aware of. its tech, its gonna get better- ok fine, i agree, but how much do you want to wait. i mean if you want to wait get a apple MBP (or whatever it will be) the last day before you die. you will be up to date on all the tech products and you can die happily thinking that i became modern (again not your death in particular, just generally speaking

)
since tech changes again, you will always be stuck with an old model. the current 15/17" user with the i5/i7 processors- what about them? they bought damn good computers but the SB will put it down easily. should they upgrade? no. if what they have suits their needs why upgrade. similarly, if the current gen suits your needs then buy it. dont wait for a product which you have no idea about.
it would be a different case if you knew some factual things, and more rumors were picking up. sure the day apple releases the mBP you will be like, "damn. shouldve waited" but 2-3 months later you may think that "hey! i have a damn good computer after all!"
sry for the essay, but yeah SRY!
so my final advice- BUY THE MBP NOWWWW
