Should it be necessary to have a PS2, PS3 AND PS4 hooked up all at once to play?

PS4 Gaikai BC sounds like a good idea, games streamable over the cloud. But the issue is our Internet connections. My connection isn't perfect, I don't want to be dependent on it for gaming.

The other thing is our digital content purchased over PSN and our PSN Plus accounts. What will Sony do about that?

I'm still confused about how their planning to resolve these issues.

I suppose for Sony it means PS3 sales will still be pretty strong. I may get another PS3 when it drops to $200 because mine will probably need replacing by then, and I still want to play my old games.
