Rumor: Next Halo to hit March 2007 (maybe too late?)

So this is some pretty cool news or rumor if you're a halo fan.  My thought is that MSFT was holding off a bit for Halo 3 to burst the PS3 bubble.   Based off of this rumor it seems as though the PS3 should be released prior to Halo 3.  I've spoke with many people who are holding out for sony but always had it in the back of their mind that they would drop it for a glimpse of Halo 3.  In my opinion, the next version of Halo is the PS3 killer, if timed properly.  Is anyone else waiting for Halo 3 to make a decision?
