No Multicam makes X a no go for me.

Oh and the music client that gives me 4 or 5 big projects a year will be happy to know that the mulitclip projects we do
with 7 and 8 angles will have to be cut manually. I'm laughing just thinking about it.

Do you think that Apple will do the same with FCP7 than with Shake, it will become open source ?

Shake didn't become open source, although I would have loved it if it had. Some large companies paid to get the source code while it was still supported so they could adapt it for their facilities, but this ended when Shake was killed.
