I don't normally read their forums, but I got a link from kotoys's forums sent out to my email (it was a link for a Chinese new years card. Yay!)
and I noticed a provactive little thread titled

Computron and Abominus G1 KO Reissues in the works

He was spot on about the Constructicons, Aerialbots and Protectobots ko's,
so I think its fairly likely to be true.

I loved Computron as a kid, and I know this is one I'd buy for certain if it were released - even though I'd dearly love to buy a TT Encore version.
Not condoning it, but if you WERE thinking about buying any loose off ebay, now is the time to do it before they hit the market.
