Yeah, XMvSF came out before even the first edition SF3.

Selvin, Shin Shoryuken is an SF3 Super Art. NOT a Vs. series super move. Giving Ryu that move would give too much power and priority to him. Ryu is the master of the Hadoken and Ken is the master of the Shoryuken. That's the way it is.

The ONLY time Ken has never done a Shinkuu Hadoken in ANY Street Fighter game is when he's part of a Double Super in X-Men Vs Street Fighter, partnered with Ryu, and when Ryu only instigates that Double Super.

And the only reason Ryu got the Shin Shoryuken in SF3 is because he lost the Super Hurricane Kick (can't remember the actual name for this) and he needed another Super Art.
And the animation frames for that Super Art are SF3 Ryu frames. Compare the two art styles, and he looks completely different.

It just wouldn't work. Let the insides of a single character go untouched, otherwise you can't call it X-Men Vs Street Fighter, just "Some Spazzy But Cool X-Men and Street Fighter Game That's Been Totally Butchered From The Original And Is Online And Is Built In Shockwave".
