Well first it was leaked, then it was announced. Tekken 7 is coming and it'll be on the Real Engine 4 with the goal of being able to put it on any system that they want. It'll be on next gen consoles, but that probably means past gen as well if they so desire. The news actually leaked on an AOL video before director Harada could get on stage at EVO (which is wrapping up now!). UPDATE: Harada actually just announced it though he did say that it wasn't the game he was there to announce. Probably was, but whateves here's the trailer!
