Additionally I can't imagine Stuart Tyrell wanting to give Omega owners a reason *not* to buy the A9. As to XScale development the version they probably would have used (given when it was originally announced) would have been the 80200 which by this stage is *very old hat*. Also simply replacing the StrongARM with an XScale (of that vintage or a newer one) would require a substantial board re-design - and that would not benefit existing owners.
Besides the raison d'etre of ArmTwister no longer exists - you *can* run 32bit and 26bit code on the one machine (as in Iyonix) and RISC OS has been 32bitted also by ROL so again no need. Besides with ArmTwister was never fully explained *how* you'd have a StrongARM and xScale interact in a way that both code would run without horrendous performance hits (I certainly can't remember any *clear* explanation and that inspite of queries from David Ruck and others).
The best one can hope for is that *enough* information will become available to allow Omega users to have their machines maintained or (if as happens in the case of EasyKees) that a "reflash" option will be available to revive their machines. Currently Omega owners are in a state of limbo - which is not a good situation - and I hope MD can be prevailed upon to help in at least leaving some sort of structure in place such that existing Omega owners *can* be supported (and if that means making information open then so be it).
