I don't understand people having a problem with a developer selecting a few people out of this community to help them test things. Also to help them produce videos. Without Jabbers, Ralfidude and Mags, you wouldn't have a single video showcasing the F14 in they ways the F14 was showcasted until now.
For the goal of having a working F14 for EA release you need to test it in larger scales on different machines to iron out bugs that might appear under "load" and specific system configurations. It's more effective and productive for them having it tested this way. If they'd just release it untested in a larger scale, the millions of bug reports they have to work their way through would slow down development and ironing out bugs. So I for one appreciate them taking their time.
March 20 is the given release date. I can live with that. Time flies by too quick nowadays anyway.
