Well... there was promise of Amiga accelerators based on Motorola (Freescale) ColdFire processors.
Never happened though :-/
We will just have to face up to the fact that the Amiga is a forgotten platform which will only receive the most limited development, undertaken usually by tech-savvy fans.
Even the X1000 may not live up to the hype (or even reach market). It's not even an Amiga, in the classic sense. It's merely a moderately decent collection of bespoke and off-the-shelf hardware running AmigaOS.
