TOM has always hosted Toonami. The current TOM is TOM 3.5, basically an improved version of TOM 3.
As of right now, the line up (Which premiered last night with the revival of TOM & Toonami) is:
Bleach, Deadman Wonderland, Casshern Sins, Cowboy Bebop, Ghost in the Shell, and FMA: Brotherhood.
Toonami will only survive if it has a decent following and viewer numbers.
More viewers = a larger budget = more money to buy rights to air newer shows.
Plus with higher budget, we could get SARA back.
