Ahhhh well...
WiiHD/SuperWii/Wii Reality will release when the sales start to dip, will be the first system with VR concept (in the systems later life). Should be announced at E3 2011 and released Christmas 2012
Xbox 3 will be released before the rest of the competition, will be the most powerful and most expensive of all 3, should use Bluray but will also have every game available to DL. Announced at E3 2010, released Christmas 2011
Playstation 4 will be released in 2012/2013 sometime, i think this because i expect PS3 to start selling really well when the pricecut/slimline hits, also with the rise of Bluray. Anyway... PS4 will have Motion gaming with HD, have Bluray and should be BC with every PS game released.
