Every radio after the G90 has pretty much been in that same boat...prematurely released and promptly abandoned while they work on the next new thing. While the G90 is better than the rest, it still has issues that were never fixed. I would not ever consider another Xiegu radio until they have a proven track record of not abandoning their radios to move on to the next new thing.
If you really want to see a disaster, take a look at how they handled the GSOC.
