Me too!
I actually think SvR 2010 took a huge step with the story designer. It doesn't get enough praise. There's a lot of crap out there, but there are also a lot of good storylines to download and I've made some good ones myself.
As for the gameplay, they seem to be improving it by adding more grapples for 2011. One thing I'd like to see is online federations, as in ones that are organized in-game. There could be a lot of potential complications with that, though. Maybe a "Be A GM" mode in which 2 players could compete for ratings online?
This has no effect on gameplay, but it'd be nice to see the design an arena feature return. I loved that part of the old Acclaim N64/PSX games, and even the upcoming Action Arcade Wrestling has such a feature.
