Gen and Rose in SFIV!
The cynic in me says this is a shameless gimmick to grab old school fans, and that SF4's system will probably be so crappy that these Alpha characters won't be able to make the jump and it will be a disgrace to Street Fighter fans. That and really they messed up Rose's face, in my opinion.
The little kid in me is squealing with delight and hopes that Alpha 3's terrible storyline was finally retconned.
Then my wallet reminds me that I just had to pay for a very unexpected bill and spits dust in my face at even the thought of getting another gaming system.
Please let there not be a cheescake alternate costume.
