Sgolds, I am expecting we will see some very compelling 64-bit games to drive the 64-bit consumer market for this year's holiday season.
Most games don't push the bleeding edge anymore. Gone are the early 90's, where games like Wing Commander and Quake can really drive the demand for performance. Now it's all about mass market acceptance from the day of release, and if 64-bit computers don't make up a sizable piece of the pie, it won't make any sense to release games that only work on 64-bit computers. The gaming industry is way too cutthroat to take that risk.
