Halo 3 and PS3 on collision course?

Timing the release of Halo 3 to coincide with the PS3 launch seems like Business Strategy101 to most armchair CEOs. But when Bill Gates made comments to that effect, Microsoft officially backed off, presumably because they didn't think the game would be ready in time. Now that the PS3's debut has been pushed to November, analysts are once again predicting a clash of titans:

Hiroshi Kamide, analyst at KBC Securities in Tokyo said, "The Xbox 360 will now have had a year’s head start. The danger is that they could target very big-hitting titles at the launch of the PS3 just to sabotage it. If they release Halo 3 – Microsoft’s biggest selling game – timed to PS3, that will be quite damaging for Sony."

When are Tokyo  financial analysts ever wrong?
