Halo 2 - Vista Only
Looks like Halo 2 gamers face Vista upgrade according to this BBC article. If true I guess it means two things:
1) A long wait for Halo 2 on the PC (Vista won't be here before the end of the year)
2) Halo 2 fans needing to upgrade from XP or XP 64-bit
Not sure if this is designed to boost Vista sales or sales of the X-Box 360. Probably the latter knowing Microsoft. What a shame that Bungie are a total tool for Microsoft now.
