Guys, I would advise you wait for actual numbers. Those are stores report which means little.

Your source  [azalyn.blog22/ameblo.jp] no longer exsists... I dunno how reliable that source is...

So about 500k w1?

That would be crazy. There will be only two days in week one. 500k isn't realistic. Probably around 300-350k.

since when wait japanese to buy a product on day three or four? haha joking

From a neogaf member:

Spent a long time in Denden Town (Osaka's mini-Akihabara) today. Some things of note (some of this won't be directly Vita related, but I figure this is as good a place as any):

-Wi-Fi models were not in stock at any of the 6 stores I visited
-One store was selling the 3G non-gentei version (does this mean Sony already sold over 500k 3G versions to retailers? >.>)
-All 6 stores had 3G versions in stock; 5 were the 100hr versions, and 1 was the 20hr version (see above)
-Various games sold out at various stores, not conclusive but Lord of Apocalypse was only in stock at 1/6 stores, Disgaea at 2/6 stores, Monster Radar at 3/6 stores. Few other games were sold out at 1 or 2 stores.
-Used copies of Monster Radar and BlazBlue at the biggest store (no others anywhere else) -- BlazBlue had notice on case "case damage and instruction book damage" /smh people, already?
-Biggest stores were sold out of 4, 16, and 32 memory cards, smaller shops had everything but the 32 (which was nowhere)
-Zelda: SS was sold out at a couple of stores -- resurgence next week on the charts?
-The stores in general were freaking PACKED, expect some pretty crazy game and hardware sells incoming

When I checked out some stores yesterday(Sunday) they were sold out of the Wifi version(all stores had the 3g version) and when I checked again today(Monday) they had the Wifi version in stock as well.

I wonder if Sony sent out another shipment of the Wifi Vitas?

vita is expected to sell really well in japan aint it? and it should do aswell. good price and finally dual analogues. something gamers have been asking for over the years. vita needs to get with the casual if its to take the 3ds head on.

Yeah that is true. With the 16 and 32 GB memory cards selling out that probably indicates those customers are buying games from the PSN store, though I don't think we are going to get any sales info from that

Seems GOOD.
