The $30-$40 price point is entirely hearsay, though. I refuse to condemn the product before either:
a) The details are finalized
or
b) I actually find that I don't, personally, believe that the product warrants the price tag.
with point b) being the more substantive, as, invariably, that's what this will all boil down to. I generally get brow-beaten when I call Burning Crusade or Wrath of the Lich King "a waste of money", but there are plenty who consider the $90 total of purchasing both to be reasonable (which I do not, given that the base game is, I think, $20 - $30 now).
I don't mean to suggest that splitting the campaign into a base with expansions is a great idea, or anything close, for that matter. My only argument was that stating that an additional 30 hours of gameplay (a number that I don't really care to reference, if I can avoid it - I barely ever blow through games the way reviewers do) should be a free download (Sky's contention) is absurd. Whether or not you consider the price Blizzard settles on to be exorbitant, I'd find it hard to justify that a new campaign and some additional features should be provided gratis. That's all I'm saying.
The only reason I invoked SC1, WC2, WC3 and, now that I remembered, D2 is that, in the past, I haven't found Blizzard's expansions lacking in content to the point that they aren't worth the extra investment. I cannot speak toward any of the various tidbits they've released for WoW, as I don't consider mounts an expansion, and I don't have any experience with how much (or little) the WoW expansions add because, quite frankly, I don't care enough for the game to want to buy them
