In the 3/9/2010 release of the Neon Genesis Evangelion 1.11 Blu-ray release, the latest Anime Source pamphlet is included which is dedicated to just Blu-ray releases coming from the company. As with past Anime Source pamphlets, it's worth keeping in mind that none of the dates for unannounced titles should be considered solid as we've seen things slip before, sometimes fairly significantly. The pamphlet is definitely good for knowing what is in the works though and there are some good ones listed in this one.
Of titles as yet formally solicited, FUNimation has plans for these with tentative dates:
Guyver: The BioBoosted Armor Complete Series on 6/22/2010
Rin ~ Daughters of Mnemosyne~ Complete Collection on 07/20/2010
Black Cat Complete Collection on 07/13/2010
Desert Punk Complete Collection on 07/13/2010
On the other side with titles that have no release dates planned but are tagged as coming soon:
Afro Samurai - The Complete Murder Sessions
Black Blood Brothers Complete
Casshern Sins Part 1
Casshern Sins Part 2
Eden of the East - Complete
Fullmetal Panic! Season One
And more Fullmetal Alchemist: Brotherhood as well.
