I haven't played a Sonic since the Genesis days but this one looks like it might actually be pretty good - as well as figuring out how to do Sonic in 3D
As far as the trailer goes it does seem like it is the going to be the funnest one since the original. If I am right it has a slew of party games built in to help it expand beyond the single player mode, these are rumors I heard not sure if it is true or not, but if it is that will be a nice replay feature. I am with Freakpizzaboy though, I think I will rent and make my final decision from there.
