Wii is already a success because its passed the N64 and Gamecube and about to pass the SNES. Also its made tons of money.
360 is a success because it improved upon the Xbox in all aspects including sales and gave the PS3 a rough time.
PS3 is successful in the sense that it single-handedly made Blu Ray beat HD-DVD (along with the Warner Bros. deal). But in the sense of sales PS3 will only be a success if it reaches 100 million (or beats Wii/360)
