I chose option 3, though I'm sure it will get closer to the 90m mark than the 60m when all is said and done.

There's only one thing I'm sure of though; it won't sell as much as the DS.

It will sell more than the Nintendo DS for sure at least 150 million.

 120-140 millions...

The people that think this is going to sell more than the DS are a bit delusional,no offence.My bet is around 100M.

On what basis are they delusional? A generation has, up until now, never seen a decrease from the previous one. The PsP2 is unlikely to sell more than the PsP. If we assume that it ties the original, you're looking at a decrease from ~ 235 million to around 170 million, or a drop of 27% out of practically nowhere.

Key words; "up until now", Sony are going to end up way below the PS2 and the 3DS is very unlikely to outsell the DS. The market is moving so quickly now compared to previous generations and I can't see any home console beating the PS2's lifetime sales either anytime soon. Not to mention smart devices, which are bound to have an effect on dedicated handheld consoles; the market conditions just aren't there for a device like the 3DS, in my opinion.

Exactly between 97 and 98 millions .

The people that think this is going to sell less than the DS are a bit delusional,no offence.My bet is around 180M.

Be moar original pls xD.

100-120 I think that the market will be shrinking due to smartphones and tablets
