mm .. i have a itch that we may see MKV on these players soon, the new ainol HDS now has it, new rockchip players have it so for chinachip to compete they will have to add MKV via updates - now, if it will work is another matter!!!!
I would say yes to that, but also i would ad don't hold your breath either, especially seeing how we do no know who is releasing this new chipset found in the HDS and other similar player. As far as China marketing goes, you may never see MKV support on the CC1600 chipset (even though it could handle it) just in order for you to buy another player with the other chipset that does support mkv.
Anyways probably in 4 months time MKV support will be standard and we won't even remember what a big deal it was to have a player that supported that particular format.
