Halo 4 9+ million
Uncharted 3 6+ million
Zelda TP 6+ million on a console that sold over 100 million
With that in mind
Halo 5 9+ million
Uncharted 4 6+ million
Zelda Wii U 2-3 million
You're neglecting to take into account the ~10 million bigger install base on PS4 compared to xb1
He is neglecting to take into an account a number you just made up in your head??
The gap right now is less then 4 million and likely won't be increasing much over the next 6 months.. $399 price cut in June.. September marks the releases of 20 or so more markets.. Novermber is Halo: MCC.. Plus big titles of COD, Battlefield, Fable and Sunset Overdrive. While the PS4 will maintain a healthy lead.. I dont think it will widen to 10 million within the next year.
I think it's going to close. I don't think Halo 5 will sell as well as Halo 4 (which didn't sell as well as Halo 3), so I see another 2 million drop. Halo 5 is made by 343 games instead of Bungie, and Halo 4 was mildly disappointing.
I think Uncharted 4 can grow another million or 2.
I don't think install base will have that much of an effect on lifetime sales, and quality of the game will matter most. If install base was so important, then why didn't Halo 4 outsell Halo 3. Halo 3 came out VERY early in xbox360 lifespan (less than 20 million xbox sold) and manage to sell 11+ million. Halo 4 came out very late in xbox360 lifespan (probably had 50 million larger install base) and only sold 9 million.
I previously made a prediction that Uncharted 2 will outsell Halo 3 ODST, and NOBODY agreed with me.
So I predict that Uncharted 4 will sell around 7.7 million lifetime. Halo 5 will sell 7.2 million lifetime. I have no idea how Zelda U will do, but I'll guess and say it will sell 6 million lifetime.
