Um... UMD had just the psp....
Blu-ray has the PS3 which is selling pretty decently now, and stand-alone players that are reaching mroe to people that don't really want a game system.
Bluray also has much more studio support that UMD has. [Since BD has nearly all, and UMD only had a few]
Bluray's are spreading faster than DVD did.
UMD.... err...
4 ≈ One
