Honestly, I'm looking forward to Fall 2011 far more than this season of anime.
Spring 2011 gave me a lot of animes that I thoroughly enjoyed - but Summer 2011 doesn't feel like it will do the same.
The premise of No. 6 sorta gave me a thought that I would be interested in it, for some reason (though on reflection, the BL undertones sorta have distanced me away from it - sorta like Monochrome Factor back in the old days).
The only anime I've found an interest in was Sacred Seven. For that, Summer 2011 isn't really up to much in my opinion
