Between 6,5M and 7M I guess :)

5M end of January
5,6M just before Japan launch
6,1M with 1st week of Japan

And in march, not sure how the PS4 will do !

That would be impressive.

Don't think enough supply, 7M os my take. With supply ir would be possible.

Will be somewhere between 5-6 million - supply won't meet demand for at least a year or so.

It really depends on the drop off. Now if there was stock sitting on the shelves, then I would think the drop off would be quicker, but as its very difficult to get stock without some crazy bundle price in a few places, I think Sony have definitely the chance of making 6million no problem. I think it depends in 1 month how stock is looking, if its still scarce in a months time, I think 7 million is quite possible. I think expecting 8 is a stretch too far right now

Can i let you know in a month or so ;)

No chance, I think they can reach 6 million though, depends on how much pent up demand there is after the supply issues since launch. 6.5 would be my guess at an absolute max but my actual guess is about 6 million by the end of March.

For the record; I don't expect the launch in Japan to be huge, 300-350k first week and maybe 150-180k or so second week.

6.5-7.0 million, not more. so i voted for 6.5 million.

Yeah i am not sure about Japan either to be honest with you. I was thinking about 350k, but still 350k would still be a nice *additional* number to the worldwide totals.

Out of interest what did the PS3 do in it's first week in Japan?

Sign me up for 7 million.
