Thanks to Samsung's closed sources, their exynos devices will never get stable cyanogenmod/AOKP roms. This one won't be any different.
Just take a look at the SGS4 xda page. The amount of development happening with the exynos octa (i9500) variant is pathetic compared to the snapdragon (i9505 LTE) variant.
i'm don't follow much about SoC stuff but why need up to four cores for the 'slow' cores? the slow cores supposed to handle low cpu intensive work so does it really need that many cores (in this case 4) to handle all the light task?
Mass production in Aug, so maybe a device in Jan. This misses xmas and if it actually squeaks into something for xmas it won't be in mass quantities. S800 and T4 will rule xmas tablets. Wait and see on phones and power use. The only question for me at this point is which is in Nexus10r2. I hope it's T4 as I want it for light gaming and prefer NV over anything else currently for game optimizations (nobody else has tegrazone like games yet) which of course NV will always be good at as a 20yr veteran of games (amd should do well here too if they last that long).
