My guess is this;
They will announce OS5 alright.
It will be available soon.
But
it will just be a replacement for TAO. Licensed off the shelf from somewhere. All the crappy games they have will be ported to it for free by their respective owners. The only thing Amiga will do is package up the games for sale like they did for the TAO.
So absolutely nothing will have changed.
Amino keep selling 10 games a week.
Kouri keeps his vehicle for shady deals.
Amino carry on doing everything in their power to kill OS4 and any other none 'DE' activity in the real Amiga market.
