I picked up the low end 2011 today for $1,099. This replaces the '10, which replaced the '09. I was digging around and found some of my old Xbench results, so I ran Xbench on the new MBP and threw the results into a spreadsheet to compare. Xbench is way outdated, so it's not scientific by any means. Shows some progression though as each model has gotten marginally better. Although I'm still somewhat disappointed in the overall spec bump (what gives having lower res than the Air??) - it is faster than the previous gen. The only game I play is Star Trek Online - which runs under Wine. FPS is unchanged, averaging just under 30 fps. So no bump, but no drop either. Thus far battery life seems on par with the '10 version. Coconut battery reports 5770 for both.
