Halo isn't as big as it used to be since 343i took over.
Uncharted 4 will sell more than Halo 5 easily.

TLoU:R is already ahead by around million. It's had great legs on PS4 so far. Now that it's being bundled with every PS4 in the US, it seems even more unlikely it will lose to MCC.
It should do around 4.7-5m LT, whereas the MCC will probably sell just under 4.1m. Just my predictions, of course.

I got moderated for saying that Halo 5 will bomb this year, but 343's Halo 5 won't outsell Uncharted 4.

Eh...you're SEVERELY underestimating Halo. Every Halo has outsold Uncharted (as much as I love Uncharted). I wouldn't go that far to say it will outsell Halo 5 "easily". Halo will sell....period. It's going to sell on the level with Uncharted or even better. At least in the U.S. and U.K. it will. I'm looking forward to both games.

Not easily, but it got a decent shot because of the big difference in install bases.

Lots of xbox360/halo people either switched to PS4 or do not plan to get a xbox1.  I do think the Halo franchise is in a decline.

Well TLOU was already showing better legs than MCC before the bundles(MCC dropped hard after 2 or 3 weeks) and now with the permanent bundle tlou will win for sure.

Yes, it makes sense to think that some of the customers of the 360 versions of Halo now have a PS4 and won't be able to buy the game. Anyway, we will know the exact impact this year.

TLoU outsold HMC even without the bundles. Now that is included with every PS4, it will sell even more.
