Like the poll says do you believe the 8th generation ( PS4, Xbox One, Wii U) will end up like the 6th generation (PS2, Xbox, Gamecube)? This is in terms of sales. 

I hardly think so. The Xbox One is getting a lot of bashing, but it's coming from a 77 million install base. The Xbox appeared with a 0 install base.
It might take some time for Microsoft to catch up, but in the end, I think we're about to see a pretty balanced generation.

Although the Wii U does have the potential of becoming the next GameCube, I'm calling it a big question mark right now. You never know.

Of course not. No generation in the future will, and the PS4 certainly seems like no PS2 to me.

Doubt it. Microsoft will lose a few customers, perhaps, but that's it. The average person has no idea all of this is going on. They'll say, "oh, new Xbox? Sweet," and buy it. They might get a surprise later, or they might just trade in games at GameStop like always, without ever knowing anything is different.

I still think it's going to be close. The Wii U might even end up close, thanks to that one year head start.

I think it will end up being comparable, but much less lopsided. Gen 6 sales were something like 1 GameCube and 1 Xbox per 5 PS2's. I personally expect the PS4 to win by a decent margin, but not ever break, say, 55% marketshare.

No way, not even close.

Lol no way.

Waaay too early to tell

I think it will be similar bit all with slightly higher sales tho with the exception of Sony.

I expect both X1 and WiiU to be in the mid 30s or 40millions, Ps4 probably 50-60million.

I think it will be similar in the fact both gens sell about 200m bur I think it will be distributed differently.

6th gen

PS2-155m, Xbox-25m, GC-20m

8th gen

PS4-100m, One-50m, Wii U-50m
