According to this they are indeed nerfing characters. I can see the difference in the wall game and the blocking while in tech roll coming into play.
Slated release in Japan for Tekken 5.1 is the first week of July. No word yet on an American release if any.
Special thanks to DUK2000 for providing some of this early information. This is unconfirmed info as of yet, so take it lightly. We’ll find out the truth as it arises. Disscuss the changes here. Top post will be updated as more information is added.
Cosmetic changes. You can now see 5.1 sported in the T5 logo. Also lifebars have different colors now.
Big changes with things in the system. You can now fully block while in tech roll state. Sucks for tech catches. But it adds more to the mid/low/throw mixup.
Ground moves do only about 70% damage as opposed to 100% and possible CH damage before.
Wall system has changed slightly. Here’s some character exclusive information that has been changed.
