I think this thread should be moved to the android section.
I've received mine, it was quite an impulse buy, and I was worried to be disappointed once received...
It wasn't the case, let's say in comparison to the S601:
Advantages of the V5200:
-Better built quality (overall plastics feels slightly better), the triggers/buttons are softer (on S601 they make a loud click).
-Complete D-Pad (S601 is in two parts)
-Better wifi (much better range).
-Better screen (5inch)
-Better touch screen (very sensible, it's resistive but you don't need to press hard to make it react, I'll say it's a nintendo grade quality touch screen, resistive... but a very good one) + 2 point multitouch for zooming (not accurate enough for presice task, it detects two points but not exactly where they are).
Let's say out of 5 for the touch screen quality: S601: 3/5 V5200: 4/5.
-mini hdmi out.
-charge via DC in (faster) or usb (slower but I prefer since it's easier) (the charging/power leds works, red while charging, off when done).
-Rooted out of the box, I've used titanium backup to get rid of the useless chinese apps/keyboards
-Weaker Cpu/gpu combo, especially since the S601 got it's 800mhz+ update.
-Less RAM, only 256mb, taking out what the gpu uses + what android uses you only have 70mb of free ram (not counting inactive ram but that's still a lot less than the 200+mb of free ram of the S601).
-The firmware files seem to be much harder to mod.
-Now that jxd are in an android console release frenzy it might be hard to have a community behind every single console they make.
On the overall I'm happy with my purchase, I'll say I'd recommend the V5200 over the S601 if you plan using more like an internet browsing device/video player thanks to it's better screen and touch screen, most emulator also seem to run fine up to N64 (although some high requirement games might lag).
S601 is more recommended if you don't really care about the touch screen or the real HD output and really want the best 3D/gaming performance and a more future proof device (cortex A9, the S601 might run fine some soon to be released 3d intensive games where the V5200 already shows it's limits in term of power).
