Since when does a Chinese manufacture (OR any manufacturer) continue to improve a product when it becomes obsolete and reaches eol (Never!). I'm sure Dingoo-Digital has done just about everything they see fit for this device, are ready or already have moved on to something else, while continuing manufacturing of this stable and matured device (In there eyes.)
The point is; dingux can continue to improve as long as there's a community behind it. The native OS has already been superseded in almost every regard including applications, emulators & functionality.
Once dingux becomes slightly more mature to the point of zero corruption issues and easily installable, other functionality such as the Tuner and TV out will becomes higher priority's for the geniuses behind the already brilliant work we've seen. To the point we could see the dingoo shipping with dingux as the native OS, probably just wishful thinking but it is possible if it continues with the support and enthusiasm we've seen.
