Microsoft confirmed that Halo 2, scheduled for a launch today, will be pushed to the 22nd of May. We have been waiting for almost two years to get this game converted to a PC and we can live with it being delayed a few more days.

According to Microsoft, the game has been pushed back "to make some improvements to the install experience and address other technical issues.". As we wrote earlier, Halo 2 for PC will feature a new map editor and will only run on Windows Vista.

What a surprise that Microsoft did that. Maybe they want to force you to upgrade to Vista.
