I'm still not sold on the 60 player matches, the only word that comes to mind is clusterf*ck.
The video made Resistance look like just another run and gun shooter in the vein of Halo, which in and of itself is not a bad thing, but I think it may be a poor mix with the horror themed story. I think Gears' style of combat is a much better fit.
Both will sell well though Gears will sell more. This video gave the multiplayer edge to Resistance, but I think that in the long run, the community will be stronger for Gears.
