Steam Summer Sale 2012 ?

Sorry if anyone else has covered this, but I haven't seen anything. When does the Steam Summer Sale 2012 start? I want a few games, but don't want to end up buying them for full price when I could get them in a sale ^_^ When is it?   Thanks.

I think you are looking for this thread.

Later this week is one rumor, I guess? In that other thread.

I believe the sale starts in 2 weeks time. As the link to the official thread has already been posted here, I'ma just lock this one up.
