How long before support for PS3 ends?

Since some of PS4 launch titles such as Watch Dogs and Destiny are being made available for PS3 as well, how long before production for PS3 games eventually phases out?

After 2014 I doubt we'll see another major release at retail (besides Bungie's shooter MMO) for current gen consoles. But indies might support them for a while longer.

It depends entirely on game sales for the systems. Developers will focus their resources where they feel they can get the best returns for their investment. Normally it's only a year or two at most the last generation platforms get decent support. Though in some cases support stops even before the new systems are out. That doesn't appear to be happening with the PS3 or 360 as the majority of the known upcoming games are coming out on these systems. 

Hopefully not for another 3+ years.

considering how long the ps2 ran concurrently with the ps3, it will most likely be a while before support for ps3 stops

Probably a few years at least. The PS2 still got games released for it for years after the PS3 came out. Not a stretch to assume the same will apply for the PS3.

Pipe dreaming but I hope support for PS3 can co-exist with PS4 for a few years. Would hate for the main focus to be on PS4 with some cool titles for PS3 still coming out. I assume there are still plenty of people besides myself not ready to make the leap of faith into next gen so soon.

4 or 5 years

I'd imagine tell 2014, early 2015 the latest.

Not as long as the PS2, that's for damn sure.

I'd guess no more than a year? I don't really know.

Atlus will get at least 3 more years out of it.

So we have Last of Us and Beyond: Two Souls coming out this year; these are pretty big titles. And after that we haven't announced any new software for PS3."'

Keep in mind of all the companies currently offering video game hardware, Sony is known for sticking out support with prior gen equipment the longest by far. 

Probably pretty quickly. Developing for the PS3 has proven to be a pain, so I imagine they will move away from it ASAP. I highly doubt it will last anywhere near as long as the PS2.guynamedbilly
