According to Rich Johnston we may be seeing the following after the Crisis wrap-up:
A streamlining of the Batman and Superman titles. Batman's losing two and Superman is down to two: Action Comics and Superman.
A new Flash.
A new Wonder Woman.
Hawkman becomes Hawkgirl (probably due to the latter's massive exposure through the Justice League cartoon).
Mystery in Space
Brave and the Bold
Green Lantern Corps (this one's pretty much verified)
More info as I discover it.
