Speaking from personal experience, I'd never buy as many new release games if they all landed in the holiday season. Looking at this year alone, I've bought and played more games than ever. If Tearaway Unfolded arrived during Christmas, I never would've gotten it, for example.

Did they have a good AAA lineup in 2015? By their own admission, no.

Did it affect sales? No?

So then why should they care? Why push their own titles back to when lots of big holiday titles are launching? "public perception"? LOL.

No, they should just release their copious amounts of awesome looking AAA games slated for 2016 when they're ready.
I mean next year there's 1)Uncharted 4, 2)Ratchet & Clank, 3)Horizon: Zero Dawn, 4)Gran Turismo 7 (not shown yet, but confirmed by Kaz as coming before 2017), 5)Ni-Oh, 6)The Last Guardian, 7)Gravity Rush 2, 8)RIGS, 9)Yakuza 6, 10)King of Fighters and 11)Without Memory.

There's probably also going to be Dreams, Deep Down and Let it Die as AAA releases.
Let's not also forget the huge Indie releases which are also very likely releasing next year like WiLD, Rime, The Tomorrow Children, Alienation, Shadow of the Beast.

That's 19 exclusives. The games announced at each conference are likely coming within the next year of that event, because there's no point mentioning something further than that from release.
Guerrilla Game's last 2 releases both came out only 9 months after they were announced, hell even Bloodborne (which is a new IP) did that, a lot of what's already been handled in Sony's conferences this year are more than likely coming out before the Fall next year.

Horizon, RIGS and The Last Guardian are more than likely landing before the Summer next year, since they're all being shown at various events and all have at least had gameplay shown to the media, running on PS4 hardware too.

What is better about it?  Just specs (albeit barely)? Its missing some features I use, I use my phone to send downloaded movies and tv shows to my xbo from phone or PC, can it do that?  Can it use external hdd support yet?  Game streaming is something I use most of the time now so my input stays on PC.  The ps4OS looks like it was created in 2005 with Web 1.0 tech.  Sure some people like the simple look but I don't know anyone that would prefer an iPhone 2 UI to the iPhone 6's.   No one acknowledges which is better, its all opinions.   I mean there are a couple games coming out next year on PS4 I am interested in and will probably get one then just to have them all.  

Like I said, the game release dates do not matter, it will continue to sell in crazy amounts.

Nope. I believe games should come out when they're ready. If the game console has to have a sole strategy of releasing major first party games at the end of the year to move units, then that would make me leery of owning it.

I see, either way, I wouldn't be for delaying a game outside of needing more work... : /

No. I really prefer spreading games out. Games should have moment to shine rather than all of them competing against one another.

Yeah, that is what would most likely happened if a game was delayed to spread out releases, may as well make use of the extra time, haha.

Well, let's not exceed in the opposite way, releasing a couple of first party AAA titles during the last four months of the year can make sense for profit, while at the same time it leaves third parties the lion's share, keeping them happy to work on your platform, then biggest third party efforts at the end of the year and biggest first party work for the rest of the year produce a steady flow of games that makes the users happy and the platform healthy.
Anyhow, I agree with you about first parties avoiding to flood the end of the year, just not about totally deserting it.
