If they do launch it at 150, I'd guess we'll see a 50 dollar price drop in under 6 months.
Going off a post partway up the page, I'm trying to think of what games actually used the XBL Vision camera in a good way. There were not many. Burnout Paradise was great between license pictures and "you just got
ed up, we're sending a picture of your face to the guy who
ed you up," I think one of the Command & Conquer games had a "gloating period" for the winner of a round. Uno was ok for laughs once in a while.
That's all I can think of, although someone else may have stuff I forgot.
Companies just don't learn from history when it comes to non-standard/add-on peripherals. Goofy motion controllers, cameras, CD-ROM drives, whatever...they never catch on like companies seem to think they will.
Someday, someone will get it right, which is why I MS is trying I suppose. I just don't think this is going to be the exception to the rule at this point.
