So basically MS is selling at $150 to break even rather then lose a lot of money right away. I think thats a smart move if thats the case.
However if its only $100 and the source is wrong then MS should drop to $100 and break even at the start, and make a few $ off the games sold seperately.
I'm assuming MS just really wants to capitalize on the insane holiday buyers/rich folks at the $150 tag.
It's just that simple.
