Could be MVA/PVA too. =) Who knows for sure. I guess just calling them TFT is simpler since IPS is AKA Super TFT.
My Wopad I7 has TFT and looks pretty good. You can see the difference with my U30GT (IPS) but getting 8" at lower price makes up for the display difference. ie, 8" RK3066 IPS would sell for $170-185 shipped.
Teclast is very good for build quality but seem to be lacking in firmware upgrades lately. No idea when or if you would get Android 4.1 on P85 Dual.
A 8" 4:3 gives about 50% bigger screen area than 7" tablet. Though, 4:3 will stop some (or many?) "higher-end" games from being playable. ie, some (or many?) "higher-end" games are made only for 16:10 aspect ratio. ie, Gameloft.
I also noticed 2 other 8" RK3066 tablets but have not confirmed if real or not. Momo8 Dual. Chuwi V8 Dual.
