"THQ’s enhancements and additions don’t end there either. Though the developer has yet to unveil its Universe Mode for this year, it has shared its latest addition to its Creative Suite. In addition to creating rings, players will now be able to customize their own stage sets, even going so far as altering designs past and present. Did you like the Smackdown (’01 - ’08) set that featured a fist smashing through glass? Maybe you don’t want the fist there though. Maybe you want to paste a giant Summerslam logo on the entrance platform. You can do that - and plenty more. For those wanting to adjust every last detail of WWE ’13’s wrestling world, THQ will allow that - plus the ability to share those creations with the community online."
Obvious natural progression of the mode, but it's Yukes/THQ. Didn't think they would just 1 game after adding the mode. There's tons of other information in that article too.
