Don't think so.

Feb: SFV
March: Uncharted 4, MLB
April: Ratchet & Clank

May-September: Gravity Rush 2 & Last Guardian

October/November: Horizon/ GT7

All different types of games, with a good spread throughout the year, at least for the games Sony has a direct influence on. Third party exclusives may be a different story. It is hard to say, because timing throughout the year is a factor, and right now games like Star Ocean 5, Nier 2, Nioh etc could be scheduled for release at any time in the west.

The 2016 lineup is filled with bigger games though. Of that 2015 list, The Order, Bloodborne, GOW III R, Everybody's Gone to the Rapture, Until Dawn and Uncharted: NDC are the ones which are fairly or big hitters.

In 2016, the big hitters are Gravity Rush 2, Uncharted 4, Horizon, KOF 14, SF V, TLG, Hellblade, NiOh, No Man's Sky and Ratchet & Clank. Likely GT 7 as well. So competition between big titles will be more. Also notice how many of them are new games, so probably need to sell better to make a profit. I didn't even count PSN only games like Wild and Rime which might be released next year.

Deja vu.

2011 PS3

Feb: Killzone 3, LBP 2

March: Infamous 2, MotorStorm: Apocalypse

September/October (Don't remember exactly): Resistance 3

November: Uncharted 3

We know how many of those games flopped (a lot) so its likely that so many games will likely not all sell well.

And all in all I'm also counting third-party exclusives, though I understand that Sony doesn't have control over them.

Your big hitter list looks a little optimistic.  The bolded games aren't gonna hit the casual market nearly as hard as the ones not bolded.  Also, there is a lot of diversity in the line up.  Flexing release dates to not have 2 racers or 2 fighters come out in the same quarter is really all the maneuvering they will need.

The core market wouldn''t buy the bolded or some other games either with such a huge lineup. Time and money are an issue for many.

Well the good thing about Playstation fanbase is they don't have a generic identity.

speak for yourself please.

in my eyes this list of coming 2016 games tops the line up of the whole PS3 era.

You are basing that on the idea that a "core market" consumer also plays all of those genres.  By definition I am a "core market" gamer, I own all consoles this gen, I participate in an online gaming forum.  In that list I see 2 games I am buying at launch (Uncharted and Ratchet and Clank), 2 I will keep an eye on (Horizon and NiOh), and 7 games that don't interest me enough to warrant a purchase.  Your personal list might have the same numbers but completely different games.  The diversity is what is going to continue to expand the userbase.

ehh, the problem is, you're attributing "flop"(ing) with releasing too many in the same year.
In reality, the problem is that while those games carry a certain weight of being big releases,
Motorstorm was not a poular franchise, similarly to lbp, and resistance...who's popularity in sales generally came from being early release titles for the platform and were generally not "great" games. 

Killzone 3 ran into the problem of not being as good as 2, similarly with uncharted, though uncharted 3 sold well.

Not to be disparaging, but I think you're overthinking it.

TBH, the only games in 2016 that will sell really well are uncharted 4, GT (if released), and maybe last guardian.
Don't expect too much from the other games. R&C might see a resurgence from the lapse between titles, but R&C has never been a huge seller.
SF is a game in a declining genre. Gravity Rush.... maybe 2m if it's lucky. Last Guardian is a complete toss up. It could sell 4m, or could be another Order1886.

Playstation titles don't tend to be blockbusters. They sell relatively well, but they've never been really solid.
However, third party (historically sony exclusives) like ff15 will crush. Just like mgs5 will do this year.
