I think if the new Amiga is to be a succsess i would suggest that just like when the first A1000 came out back in 1985, the new Amiga must be GROUND BREAKING, not just a machine which can run OS4 etc...
Nearly impossible today, simply too much competition.
They should design a games console, but more powerful than the Playstation3 or Xbox360 with better processing power, better graphics hardware etc...
Again, nearly impossible - if it was possible, Nintendo and others would already be doing that.
From that they should turn it into a computer with expansion slots, built in wifi etc.. and have it packaged with a Amiga branded keyboard/mouse and the latest OS4.
Latest OS4 lacks fundamental features that both developers and users expect to find in an OS today. Noone outside the Amiga community is interested, and the few who might be, quickly shun off once they see what state the OS is in.
With such powerfull hardware and maybe a good ad campaign they could get 3rd party support for games (such as from EA or Activision etc...)
OS4 lacks fundamental features for being interesting for games developers.
Maybe in the future even release a smaller version (with no Xorro/PC slots etc..) and it would be a kind of moder A500 games machine yet still a computer at the same time.
All the games consoles today already are usable as computers, there's lots of software for them already, to be bought online.
