Since they're billing the entire thing as the first HD broadcast (and since the HD boxsets of season 2 already exist) I'd assume not. It's already been possible to view non-remastered TNG on HD channels (chances are you can still find it airing on Sky Atlantic).
I know I'm looking forward to it. Season two may not, overall, be one of the show's good years, but it has more good episodes than the first year ("Contagion", "The Emissary", "Elementary My Dear Data", "A Matter of Honor") and, of course, two of the best episodes of the series run ("The Measure of a Man", "Q Who?").
