Probably not anytime soon. Root is a plus, you can use all kinds of root apps and delete bloat. I wouldn't put money on having custom ROMs anytime soon, we don't even have any kind of custom recovery yet. Oh yeah, and our bootloader is locked which means for the time being we can only use 2ndinit recovery and ROMs, like the Motion uses. I have personally tried Motion's 2ndinit recovery on my Premia and it won't work, needs some tinkering.
Not trying to be a downer here, I'm just letting you know where we stand with post-root goodies, which is still nothing..
