The A1 is dying, as Mr. Eyetech himself conceded. There simply is no new design in the works, what you see is all you're going to get. AOS4 however is not dying, at least not as publically as the hardware it runs on. People are indeed using a beta version; the developer's version went gold last year, IIRC. I suspect (that is, s-u-s-p-e-c-t, as in 'my uninformed opinion', disclaimer, disclaimer) it will go gold for ordinary users before the year is over. But as cecilia already indicated, people who use it are enthusiastic, and that's a good sign.
