I don´t know why everybody will have the A7 prerelease! It is an alpha version from A7, not more. The really good things come later like it was with A6.

I´m happy that i have A6com, and use it so long as i want. When A7 comes out, everybody can test the A7 demo and upgrade after that.
Please, stop with all if it is fair or not. When you have the last A6 version you have a stabil version, A7 is in the beginning and is maybe full of bugs.
