100k

It is possible if they give it away for 5 $

Yep. That's if Sony advertise it heavily and it really does well. 

If not:

America: 35k FW, 100k LT

EU- 10k FW, 30k LT

Boost for Vita- 1/2k, 1 week only. 

People are bigging this up too much. It's a niche title that won't sell, unless Sony show it off, 

I highly doubt it'll get anywhere near 100k Frist week in the EU/US, I reckon about 50-55k frist week about 30k US 20K EU.

Perhaps I was unclear. By 'bigging up', I meant in both quality (though this is only something which I can decide when I play it), and also its selling power to push HW. You'd be surprised, it was just a month or two ago where people were predicting this to be the Vita's first 'killer-app'.

I personally cant wait to get this game! The reviews all say it is an amazing experience and beautiful design and concept... should have it tomorrow which should give me enough time to finish Rayman: Origins

i haven't seen any actual data for digital sales -- just vague comments like "strong" and "exceeds expectations" which can really mean anything.

i doubt digital to retail is as high as 1:1 but i think there is a strong digital market.  I myself am only buying digital for instance.  maybe 1:2 is the right ratio.  hopefully we get some real numbers for something at somepoint to at least get a decent ballpark of that ratio.

4Million first week. People will buy this game even if they don't have a Vita because it's a great-looking game.

After 2 hours I'm loving it so far. Only "falling" around the city looking for gems is so much fun! Don't expect any publicity for this though, as they weren't even able to translate the spoken parts to English...They're not spending a single cent more than needed for this.

Yep and those who didn't preorder it will be tempted to buy it digitally to get the free DLC in week one as well.
