Pretty much all the big third party games are still for 360/PS3, some big examples include

Destiny

Watch Dogs

Titanfall

and probably a couple more I missed but you get the idea

I say it will stop maybe late 2015 or 2016 at the latest

Hopefully next year.

AC: Unity is XBO/PS4/PC only...

Otherwise, companies will stop making games for last gen when they feel the potential money they can make from last gen sales is less than the cost of porting*negative effect on game quality

Income<Cost*Quality Difference, where QD=1 when last gen ports do not impact game quality

AC:U is completely next gen. It's what they promised after AC4.

So it's good guy Ubi I guess ;)

When console manufacturers create a safe atmosphere for them.

In 2016 we'll see the last AAA game for the PS360. Indies will continue to develop for the systems after 2020.

Why? Not only are they shitty to develop for, but in 2020 no one will use them anymore.

Probably no more cross-gen titles in 2016. Tomb Raider will probably be the last one.

But the exception will be sports games. This is the first year EA will not publish FIFA for PS2, so the PS3 version will probably end with FIFA 19.

I'm thinking of those companies that released games for older consoles many years after the console was abandoned (Pier Solar is releasing on the Dreamcast and the Sega CD) or those unlicensed games on the NES and the 2600. If they managed to make profits of dead consoles, why not making it with the licenses and the advantages of digital distribution?

When the sales of third party games on those platforms becomes uneconomical to continue support. Games like sports games where the engine has been written and all it takes is an updated players list, I can see support 4-5 years from now. New games that are built from the ground up I can see starting to skip last gen in another year or two, end of 2016.
