As much as MS would love to see XBox be the only console contender, it's never going to happen. MS was lucky enough to catch the OS market at the right time and monopolize there, but the video game industry is a completely different story. It doesn't take much to design a console anymore and there are tons and tons of able game companies that have been putting out great games for all three systems right now. MS won't buy them all and because of that there will be other contenders.
