Considering the fact that both games are going to be released for different platforms, I don't think so.Isn't RE6 coming out around that time as well? Hopefully the game won't get buried by the attraction and blitz that game will bring.
Capcom might lose some points though because they (more than likely) are going to release a faulty RE6 and 2 months after they will release the Gold Edition.
And even after Gold we might get the Super Ultra Platinum Edit of RE6...
