He'll still be called the Flash, but as far as we know, he won't actually be appearing anywhere except for the occasional guest spot. He's off the JLA for now, and Titans is focusing on Deathstroke's team of villains, and Flash is all Barry.
Going by Dan Didio's remarks that our "Flash fix will be Barry Allen, pure and simple, for 2010," I wouldn't expect to see Wally much at all for a while.
That stinks. If he's not going to be in the new FLASH book, he should at least be in JLA. Imagine him working with Dick and Donna as part of the big leagues (no pun intended).
