so you want them to add a redundant prepritary format that has no advantages over Flash memory based media and adds cost and battery drain onto their next handheld (UMD drive) plus would increase load times (flash based has no seek time and could have faster transfer speeds)?
No Nintendo won't move to optical media for the DS2
PS nintendo would have no problem paying Sony to use a format if the format benefited them. and little to no money the would pay for Blu-Ray would go to Sony.
