They are battling the mighty Sony to a draw currently (slightly winning but fanboy will scream year head start, even though many used to say that PS3 will wipe out all 360 lead in a month or two), so that alone I think has far exceed MS expectation. PS2 outsold Xbox by like 5-1 if not more last gen, this gen they are keeping on par with PS3 sale so for MS I would think it's a success.
Sadly they (Sony and MS) both underestimate Nintendo return to the throne.
