I don't think XBO numbers will be as high this time around as 360. Mostly because now there is no point in owning both consoles. By that I mean you would have to pay two subscription charges so I think that will stop a lot of people that might have bought both consoles such as people buying a 360 and also a PS3.
Another factor to take into account is second purchases. I think we all know at least one person who has purchased a second console after theirs had failed. I had to buy a second PS3 :@ Judging from early analysis though, this current gen seems to be of better build than the previous gen, so many this will lead to less purchases too.
