Seems somebody at microsoft finally got around to seeing what their old pal Gabe's been up to down at Valve. Imagine their surprise when they discovered old Gaben's been raking in the dough like a fat man well raking in shitloads of money. sorry there's no analogy. Gaben is fat and rich.
So they come back with Live! Whether it's Live as in live with windows or live at windows, we can't know for sure. However, this is the only problem they have to focus on now that they've cornered the online gaming market.
