I remember when I purchased my PS2; XBOX had been out for some time. Because I didnt have a DVD player, my first concern was a DVD player, then gaming. Because the XBOX needed a remote/addon, I went with the PS2.
Someting this small CAN sway a descision.
if MS released a BD addon for the 360, it might steal future PS3 customers away, that think the same way I did way-back-when.
We ALL know the 360 had far more quality games than the PS3... why not take away the last real reason to buy a PS3?!
MS made the HD-DVD drive an option for a reason... it would be a shame to waste the flexibility.
