No you're ignoring the fact that more 360 users playing batman is something that could CHANGE how it works in terms of sales. Installbase is only a small part of the issue.
No demand for the limited edition console being high isn't a fact, because we only have pre-orders to go on and we have no idea what the pre-order numbers are,. It's not a fact because you say it's a fact.
Also believing PS4 will break 350k in June is not a fact unless you are from the future. You seem, to have no clue what you're talking about. Me saying I don't believe PS4 will break 350k or be around it in June is an OPINION, and that's something you have not attacked OTHER PEOPLE for except me, mostly probably because I'm a junior member.
Also, a user posted an LTD (i don't recall if it was AC or AK) saying we don't have the LTD but 360?PS3, so no it's not just launch month numbers I'm using or has been posted by other people.
Also your last sentence is moving goal posts because you were arguing before it was the 360 installbase, now you're syaing the PS3 may have outsold the 360 version in the long run.
But let's backpedal for a second:
And nobody ever questioned his reasoning, why? Regular non-junior member.
