"Google has said that YouTube will remain as is."
I believe this would just make everything too complicated than it needs to be for the average user; besides, the likelyhood is that the user already uses Google, so there's no need for Google to try and reel users in via a search applet (that would probs make YouTube look ugly).
And, aren't Google Accounts already merged with YouTube Accounts ?
