EvilDragon has confirmed that gph are working on a Successor to gp2x
Anyway, it has nothing to do with the Pandora, they talked to me about their new device summer last year, before Pandora has even been announced anywhere.
I'm gonna stock both and support both if there is the demand. But let's see what'll come from GPH. If it is cheap and a bit better than the gp2x, it can well live besides the Pandora.
