Sony will definitely use Blu-ray on their next console, no doubt. Nintendo is expected a HD console next and they need to put a large amount of data their. HD-DVD is dead and normal DVD holds only 9 gb. So, I believe Nintendo will use Blu-ray as well.
Microsoft may stay on DVD and try to release a console with low price without paying for blu-ray (which seemed to be working this gen), or they can use download only as their main target is Europe and USA where many people have high speed internet.
