Min 100k
Max 170k

By first week, I mean the vgchartz week ending 25th febuary. I'll add that to the OP. Oh, and if you say 100k-200k, i will put your prediction as 150k

150K

Allowing for what theprof00 said:

1st week: 450k

or 1st week (weird 3G only thing): 100k, then 2nd week: 380k


I think it will roughly start similar to the PSP (which managed 400k apparently), the PSP was an unknown (a non-Nintendo handheld?) but was hyped.... the Vita has the advantage of following the PSP, so normally I would have put the launch higher, but my limited knowledge of people's opinions of it seems to indicate it isn't that desirable.

I think about 200K, the media is totally against the PSV right now :/

Between 400k and 500k. Customers in the US don't do their research when buying things (heck they dont even look a picture menu when ordering); so they don't give a hoot about the negative press it has been getting on the internet. It will fall from there but experience stable substandard sales after that until a price cut.

Depends on what the shipment is really. I think some people are really under estimating it. You have to keep in mind that first week sales for a console are not a good indication of future sales. The hardcore fans will swarm to a system first week. As really if you are going to buy a system at launch you may as well buy it first week as opposed to a little later. You get a huge wave of titles, price isn't going to change etc.

The weird launch they are doing where the 15th is a soft launch might mess things up. But I will say whatever Sony ship for the first week that the sales for the first week (or 15th + 22nd with their stupid launch) will likely be sold through or vast majority.

So err yea. Whatever their shipment is then 90% or so of that is my guess.
