I wish they would give us some idea of what's happening with it. There was supposed to be a preview at one of the events earlier in the year, but nothing showed except for some basic details.
And They've only just started putting idea's together (according to this thread on TFW.)

I like the idea of a CW mini series, but I'm worried they've left it too late. Titan Returns starts next year, and the writers haven't even finalized stories yet.

And as someone in that thread mentioned, I really hope they actually focus on the combiners and don't just relegate them to second string characters.
