I can't understand why a manufacturer would want to discontinue a product which ( to a lot of informed customers) is the benchmark for the industry.
Easy. Humax is making little or no profit out of us. The consumer goods market is sustained by the manufacturers doing their best to sell us the next better-than-ever product, not waiting for the existing installed base to break and rely on the replacement market. The next idea is to make sure products don't last too long, but they can't go too big on that one or they get a reputation for poor quality. They can't be developing and manufacturing the next product while continuing to support and manufacture an old one.
The TV industry had a field day with the switch to digital, and then the push to larger screens. 3D TV was a flop, so they are trying Smart TV instead. Very soon they will be trying to ram 2K down our throats, and thinking they will be able to follow that up with 4K or 8K. They are dead scared that we will say 'I've paid enough for this 2D 50" 1080 set, and that's all I need', and fortunately for them there are (or have been so far) enough people with nothing better to do with their disposable income than buy the latest huge TV to slob out in front of or show off to their friends (who then have to keep up with the Jonses).
I have no intention to purchase another PVR.
Neither would I, except that sooner or later it will break and a hard drive replacement won't fix it (or a suitable hard drive is not available). I have just given up on my much-loved car, because (amongst other things) it has become unmaintainable - the metal can be repaired, but the plastic connectors etc in the engine bay are all brittle. A friend's perfectly-good-enough Windows 3.1 computer had to be replaced because the printer broke and replacing only the parallel-port printer was prohibitively expensive (USB needs Win98 minimum - and a computer with USB ports!). Crap happens.
There was nothing wrong with my analogue PVRs - but they were made obsolete by DSO. Our HDR-FOXes (and TVs) could be made obsolete by another standards shift (and wouldn't industry love that!).
