It looks great, but the initial release is missing my favorite characters. So that really sucks for me. And none of the new characters really look interesting to me.
I'll still get it, because I grew up with Street Fighter and Mortal Kombat. But I'm a little disappointed so far.
SF6 is going to be big for fighting games. I'm excited to get my hands on it. Wish I could've got into one of the betas.
