I have been on PS3 since Beta, and taken part in both PS4 betas.

I only have limited access to the PS4 - when no one else is using it or watching TV - but sole use of the PS3.

I want to be able to use both.
If I upgrade on early access do I lose my PS3 access?
How do I regain PS3 access?

Any suggestions please!
I don't want to upgrade and find I can no longer play on PS3 because that is where I have most time!

Thanks
