Well, seeing as we don't yet know how much the MacBook's design will be changing (it may be significant, it may not), it's probably a bit early to guess at whether the Pro design will be changing as well, especially so soon after the line's 'introduction'.
That being said, it sounds like what you're asking is strikingly similar to what's being discussed in
this thread, so you might want to keep an eye on that instead.
By the way...welcome to AppleNova!
