Sat - I know you weren't upset about it, but I was ('cause I went a little off the handle when there was no real reason), so I apologized. Nuf said.
Actually Gearbox didn't start development of Halo immediately after the X-Box version was released. It didn't start until some time later. I don't know exact dates, but I am sure that they haven't been developing this since the original's release.
They have had to to add a console backbone, which I consider to be a remarkable feat.
But anywho - yeah, there are problems, but I fully expect them to be resolved. Maybe not tomorrow, but Gearbox will get it done. In the meantime, I'm gonna sit here and wish I was at home playing Campaign.
