@Avinash_Tyagi - nobody predicted the Wii would be so successful. Even Nintendo has been amazed by its sales.
As for next-gen it really depends on what all 3 bring to the market. The Winner will be the company that is able to balance power/cost/software/consumer awareness. Id say that Nintendo are in the best position but both Microsoft and SONY are in a good position to invest in more powerful hardware that will be competitively priced. (think $399 PS4/720 vs. $250 Wii2).
