While I agree with #1, there is a pic from AC, and it's a pic of Ezio.
I think what's more telling about the fake is the grammar and spelling:
"Over 25 stages in which to test your skill against
oponents" (Opponents)
"20 characters
inclusing Ezio..." (Including)
"Customize and play as your own character using the
new designed 'Soul Creator' mode." (Newly)
Yep, it's a fake.

As far as this execution conversation is concerned: People who are complaining about execution in SC are crazy. As a setsuka main who plays Ivy and Yoshi on the side, I can tell you that the execution in SC is quite possibly the easiest out there already. Make it too much easier, and I'm not sure I'd enjoy playing some of the characters. There is literally nothing in SC4 that causes a lot of problems as far as execution goes unless it's a combo that you're only doing to be flashy. (Soph 66B B2

B:B236:B comes to mind)
Sure, there's inputs like Ivy CS and SS that take a bit to learn, but really it's still not as hard as MOST of the 1 frame links in SF, or 90% of tekken's juggles or BB's combos. SC is already an incredibly easy game on the execution side of things, I don't see a reason to make it easier.
