Well, I just bought the SYNERGY model from CompUSA not too long ago and it's able to fit my MBP while in its Incase sleeve. I'm sure it'll fit.
My only gripe with the backpack is that the compartment where your laptop goes does not go up all the way to top of the backpack. My MBP is sitting about 1/6th out of the compartment so the while the bottom half is very well protected the top half is somewhat exposed so that's why I use a sleeve to provide a little more protection.
