Not really, the tech isn't there yet for streaming PS3/PS4 games as the norm or ideal thing, not even close. That's why I said Streaming may be good enough by the end of PS4's lifecycle to counteract the need for PS5 in the form of new hardware. 

Almost in 2013 and we have no hints of Sony plans for Gaikai.

Streaming can not replace real backwards compatibility and is not a viable options for at least half of American.

No streaming service can become widespread in the USA until either countless billions are spent on high speed infrastructure in rural areas or some kind of new technology replaces current broadband standards.

The USA is huge and spread out. Half of Americans don't have access to true highspeed.

We will have to wait.  But it's weird that no info has leaked so far.

I really doubt Sony bought Gaikai for Backwards compatibility only.

Being able to stream ps1/ps2/ps3 games would be lovely! I don't have a good enough internet connection though so I doubt ill be able to stream anything past ps2 lol

If the PS4 has capable hardware that can stay relevant for multimedia features, and Gaikai can be a never ending evolving service for streaming/ digital games then Sony has huge potential that can reach even outside the PS4.

I think you guys don't really understand why Sony bought Gaikai. They make very expensive well made games but they are limited by the userbase on the PS4/PS3 so being able to sell these hugely polished and expensive AAA games to a wider audience will allow them to recoup the costs better, especially at the start of the next generation where it will be difficult to sell to such a small userbase.

The other part is a hedge against the success/failure of the PS4 so if the PS4 gets off to a poor start they can still sustain their game development. It isn't that they believe the PS4 would sell badly/poorly but it gives them greater confidence to take bolder steps with their game development so they can take bigger risks without as much danger from the unexpected.

Finally it gives them an opportunity to expand their PS+ subscription service perhaps to another tier or perhaps to get games from companies on a short term basis rather than just giving people games. They could use it like pay TV where you may only have access to a particular title for a limited time.

Note that I said backwards compatibility "and" not viable for half of American. I then went on to explain taht streaming requires too fast of internet speed for half America.

Streaming may be the future, but that future won't come to every American household for 20 or 40 years unless something unexpected happens.

the more functionality the better.
