"So the plan is to begin with North America next year and the plan is to provide a streaming service that will allow for PS3 content initially to be streamed firstly to PS4 then PS Vita and then PS3,” said Ryan.
Gaikai will be made available in the U.S. “early-ish” 2014, Ryan confirmed.
I'm interested to see how this works and how well. I'm done, flame on
Gaikai has stated that its streaming technology will be capable of providing instant access to game demos via the PlayStation Store.
Gaikai will enable PS4 games to be played remotely on the PlayStation Vita.
Titanfall for PS4 confirmed.
why not just make the thing backwards compatible
If you were to do a disc based backwards compatibility you'd have to fit the PS3 hardware onto the motherboard along with the PS4 hardware.
The Hardware Solution
Some people don’t understand the technology needed to emulate the PS3 on PS4, and I can forgive them for that. Some people do realize why it’s an issue, however, and have found another solution. Why can’t Sony just go ahead and put the parts needed into the PS4 and release it as part of an exclusive, limited release SKU?
Before we even get into the real issue here, let’s just say this. Even if the rest of this section weren’t true, Sony would still need to get the Cell working alongside other parts of the PS4. I can’t say for certain that it’s impossible, but it brings up some very complicated problems. What happens if you’re playing a PS3 game and press the home button? Which processor handles friends logging in and out? How about video uploads?
How do you swap between processors mid-game?
Is there a motherboard that could take both the cell and the PS4 processor and control them both without error? There’s a reason you need an Intel board if you plan to buy an Intel processor and the same applies for the Cell/PS4.
What they don’t take into account is the extra work needed. Not only paying people to work out the problems mentioned above, but then paying them to build a PS4 that houses all the parts from the PS3 without them overheating or interfering with PS4 processes. Then they’d need to market it, transport it to stores. Then they’d have to explain to the people complaining about the $2000 price tag why it’s so high. There’s just no way it’d sell.
