Halo 2 Expansion?
Gamespot has coverage of the appearance on an official Korean Xbox site of a "Halo 2 X-Pack". The possible expansion is another possible way for Bungie and Microsoft to get the heavily foreshadowed ending to fans of the series. From the article: "Such a Halo 2 expansion could be a twofold boon for Microsoft, adding another incentive for gamers to join its online service and squeezing further dollars from the nearly 7 million gamers who already have Halo 2."
Anyone who reads the "Weekly update" section of Bungie's website knows what's going on here. The game multiplayer aspect of the game has a few bugs in it, and Bungie has been working for months on ways to fix those bugs without totally ruining gameplay. Why not quietly update their buggy product, give you a few new maps and multiplayer modes, and make YOU carry the costs?
Of course this is going to start a whole bunch of people discussing whether Bungie (or MS) should release products that aren't finished, or are "Buggy." And to those folks I say: Sod off. If we were to wait for every game to be absolutely perfect before shipping, we'd still be stuck waiting for our PS2 Viewtiful Joe demo discs!
