These are excellent questions. To give you my perspective, I am trying to solve my immediate problem in data acquisition. The possible Oberon application is a byproduct, even though the board was heavily tweaked towards Oberon. (Things like PS/2, HDMI controller, or the radio module which I added yesterday). Nevertheless, Oberon cannot be my main motivation. If the community does not take this board, I still have a good use for it.
Concerning the future, Xilinx will keep the parts around for about a decade. They just extended the Spartan-6 lifetime by about ten years. I expect Artix to be available for about this long as well. The boards can still be manufactured in five or even ten years. This gives us enough time to design a subsequent platform in a couple years from now.
At some point in not too distant future I plan to release the design files. Not now, because the design is still preliminary, but once the dust settles, I plan to release. These days open hardware is becoming a norm rather than an exception, so I will follow the suit. Open hardware is generally favored by those who are concerned about the future.
I hope I answered some of your questions.
