Okay maybe I should try to re-explain myself.
The artstyle of this game resembles a 70's cartoon or simple styled cartoon.
Characters like Ryu translate well into this artstyle due to him not standing out too much (probably due to him being so simply designed) plus he could transfer to almost any cartoon setting due to him being a historical shoto.
Someone like Dante however wouldn't because he isn't designed simple as well as really looks like a modern designed character, so I 'd find him to stand out a little more.
I'm not saying that he shouldn't be in the game (because I personally want him to be and Capcom eventually will) just that he wouldn't really fit in with the artstyle to me.
Agreed.
