Sense for me will never be about the launcher honestly, I just like the little stuff here and there. Leedroid's new stripped sense is actually pretty slick, because it removes the behemoth that is the launcher but keeps all the nice little stuff. Best of both world's for me, because it speeds things up while keeping the sense-related stuff I actually want.
I'm not surprised we won't get 3.0 though in all honesty, we're not exactly cutting-edge anymore. Although I'm sure like others have mentioned, if we want it, there will be a ROM somewhere that has it.
Not going to lie I really do like the new lockscreen though.. It's sexy.
