As per the previous announcement, it will happen next month (July) but still, we don't have a confirmed date yet (or I just miss it).
I don't know what ETH 1.0 you mean. This is just an upgrade, it won't affect the previous version.

But anyway, I'm not going to excite myself but I was believing that it helps a lot especially for the transaction fees. And I think everyone is waiting for this moment to come, in fact, we have been talking about this since last year.
