IMO, over priced and really no need for one right yet it's too soon, DS is still going strong they could still ride it for a few more years. And I just have a feeling PSP2 is going to kill, Sony seems to got an Ace with this one.

Over 9000, all of them.

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 If they don't it may look outdated compared to the 3DS and without 3rd party support it will fail to sell.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.

Is this a wishful thread or some serious prediction thread? Because by some coments then I say that Wii succesor will sells more than one trillion.

But, reading the op, I think he is asking serious prediction. So, mine:

N6 - 80M

Xbox3 - 58M

PS4 - 55M

3DS . 85M

PSP2 - 39M

I predict a shorter and lower generation.

Xbox has already taken over US and UK the two biggest markets, i think by next generation the rest of Europe will jump on over to Xbox and Playstation will end up like Sega.

We don't know anything.. but we know many of the games... based on the fact that the majority of the gammers, likes playng fun games. heres is my prediction.

PS4 addon for PS3        40 mill

Box 720                         60 mill

Wii-R                              160 mill

3DS                                150 mill

PSP2                                80 mill

next xbox 70mil

next playstation 70mil

next wii 85mil

3DS 100mil

PSP2  40mil

xbox and playstation will  be neck and neck again. Wii and DS will lose the biggest % due to casuals getting their gaming needs from their iphones/itouches. These are what i think the sales will be when the 9th gen starts, not nessessarary when the 8th gen consoles stop selling.

lol unless sony makes a console that is like the wii then 300 consoles are in the past next generation the starting price will probably be 500 or something in the past. 

Not at this point, their position has been too far eroded, even now they are firmly in third pace with a $300 console

Its fun to dream, bu sooner or later you must wake up Gilgamesh
