It is not really that important to be "Official".
We can extend the life of 3.9 as much as we can, but then there is no future in it, and every step we go forward is getting more difficult and slow.
What is more important than extending the life of 3.9 with huge coding efforts, is to empower AROS guys to deliver an open modern and freely available 68k operating system for our beloved Classics.
For this, I keep my fingers crossed, my hopes high, and pray for them every night before I go to bed. 
PS: But, just in case AROS devs cant deliver, I will still try to keep pushing 3.9 forward.
You think AROS will run fast enough on 68K?
Hmmm... what I'd like to see is a Coldfire-based replacement board for 68K classics that could run OS 3.9 or/and AROS(68060 is 88 MIPS@66 MHz, Coldfire is 400 MIPS@233 MHz) that would include a more powerful gfx chip and faster bus/memory + FPGA for 68k custom chips. Atari Firebee shows the way(it costs 650 euros, pricey, but somewhat still acceptable).
