PS4 should be around 30-36 million by the holidays next year.
However, if it does reach 20 million by new years as some are predicting it will, then Sony could easily be at 36-40 million.

Of course it isn't because of the installbase difference even though sometimes attach rate is more important but zelda isn't mario to outsell or match the sales with a game that it is one a far bigger installbase...However you never know,zelda u might be the best zelda ever,it has a big hype and if it will be heavily bundled...Anyway,win of uncharted 4 is almost a given! 

Uncharted 4 will be a 10,000,000 seller people

This is so stupid. The PS4 will have an install base that is probably like triple or more Wii U's next holiday. Of course UC4 will sell better. That's just logic. Zelda U will be the better received game though, calling that now.

Uncharted 4 will sell at least 8 Million lifetime if growth & PS4 sales are any indication.

Well, duh! Uncharted 4 will easily reach 8 million, while Zelda U will probably reach 5 million!

Where is the bold part to this??
Zelda is on WiiU, so expect sales more like WW (4.6m) at best.
UC4 is on PS4 and has grown in popularity. Plus after TLoU ND have gained more attention with both core gamers and the more casual ones.
I would go ahead and say UC4 doubles Zeldas sales.

Twilight Princess on Wii has outsold every Uncharted game. The UC games beat Skywayd Sword, but that was a big sales letdown. Requiring an additional accessory and being released when the system was considered dead certainly didn't help.

Only way Zelda would outsell UC is if the later released for 150,00.

In other news ps4 will outsell WiiU.

My predictions:

Uncharted 4 will outsell Zelda - 8 millions to 4,5 millions.
Zelda will outsell Uncharted 4 based on copies / install base. 1/10 for Uncharted and 1/4 for Zelda
Zelda will win game of the year over Uncharted 4
I will enjoy the **** out of both games

Cant wait =)
