You would think that they would bundle the expansions with the current release.
Original Game: $19.99
Burning Crusade: $12.49
Wrath of the Lich King: $19.99
Cataclysm: $39.99
Now these are all retail prices but at $90+ for $35 in BTC, if it does indeed have all the expansions is a good deal. But honestly, couldn't you buy the original game then just add in Cataclysm and thus get a level 85 without buying the other 2?
Thus my original question was valid.
