Was waiting for this review:

Looks like the 13-inch model took a bit of a hit in Windows for gaming due to the integrated HD3000 on SNB vs. the NVidia 320m used in last year's model. Shame, as that's the cheapest (if you can call any MBP cheap!) and most popular model.
On the 15/17inch models they mention the biggest shortcoming as extra heat and potentially worse battery life due to using quad-core i7s. Strangely regarding battery life it came out ahead of last year's model in 4 out of 5 of their own tests... the only one where the new model was worst then last year's was when constantly running highly loaded multiply threaded tasks in loop, not really a task most people are doing when on the road. They mention this again in the conclusion - and although technically true, their own tests show for most people that battery life would be better. Other then that pretty objective review.

Thankfully none of the shortcomings seem a deal breaker, bit of a relief as mine's due to be delivered on Monday!!
