I think a blu-ray variant will be used for the 720.
However, for the 'Super Wii', I think it will use a propriety format based off of HD-DVD . I believe this because a single layer HD-DVD can hold 15gb, with dual layer holding 30gb. Compare this with Wii DVDs which can store about 4gb for single and 8gb for dual layer. To my understanding, no Wii games come on multiple discs and only 3 are on dual layer (SSBBrawl, MP Trilogy and Metroid Other M, though I'm sure The Last Story will when released). A roughly 4x jump in capacity should be more than enough for the Wii's successor. The jump from GC to Wii was only 2x and that's worked out fine, plus several GC games came on multiple discs (MGS TS, REmake, ToS, BK, etc).
