Nintendo 6- 140-160 Million
Xbox 3- 60-110 Million
PS4- 30-80 Million
3DS- 180-200 Million
PSP2- 20-30 Million
iGame?- 10-100 Million
If Nintendo can pull things together like Sony did when the PS2 came out the Nintendo 6 will likely sell more then the Wii and a much stronger 3rd party support.
Depending on the casual market on the Xbox 3 and how well it does in EMAA and Japan. Most likely in Japan the Xbox 3 will be in last place, EMAA much harder to predict. If Microsoft captures the European market then it could push over towards the 100 million mark, in the best case Microsoft captures the Japanese market and it pushes to 110 million. In the worst case it may only push up to 60 in 2nd or last place.
If Sony learns the mistakes they made with the PS4 and recaptures the American market it could push upwards of 80 million consoles. But if they make the same mistakes as they did in 2006 it might lose 3rd party support and sell only 30 million.
The 3DS will sell slow at first but in the first few years when Nintendo lowers the price, sales will explode and in it's 15 year life it will push 150 million .
The PSP2 looks like it will be sadly ignored by 3rd parties and it may cost quite a lot if Sony tries to make it like the phone. If Sony makes it like the phone it may be crushed by the tight iPhone, Blackberry, Android market. If they don't it may look outdated compared to the 3DS and without 3rd party support it will fail to sell.
iGame is very hard to predict. Since it may not even come out. If it gains huge 3rd party and a developing 1st party support it may be in 2nd place, but it may get crushed in the competition and sell only 10 million consoles.
This of course is just a prediction I thought of in about 10 minutes.
