No new kernel, but there is from DMM new OE for 800HD to (like to the others boxes) - OE 2.0 ...
There is not going to be an OpenPLi 3.0 for the 800 and the 7025.
Dream Multimedia doesn't supply drivers for the kernel version it uses (looks like they've stopped development for those two models).
Yes with a lot of work(arounds) to get it working now and in the future.
of course .... but is the same "a lot of work" with others boxes (with new kernel with OE 2.0 and OpenPLi 3.0)
