I remember something. When I take first TKR, All males & famels have faces from TTT2, later in version 1.02, all female have a new faces. Maybe he take face from version of 1.00 or 1.01. Cuz there Leo & Alisa's faces was still from TTT2.
True, they are updating still. But I'm sure Tekken Revolution will be famous now till next year. In next Tekken (might be 7, but I know some people told me a secret what will be before Tekken 7 - I can't say what it will be) Namco will remove 70% of characters from Tekken. We can expect that some pretty good characters will be deleted. The one choice will be between Christie or Eddie. And there will be groups, f.e: Mishimas, Ninjas etc.
