There'll be no select on Iyonix in part for political reasons (the success of Select now seems tied to existing users and the Omega).
There may also be technical ones (is Select *all* 32bit neutral - if not it could only be emulated using Aemulor - surely a bit of a retrograde step ?).
The thing is Castle may not have asked ROL for a 32bit OS (I am not privy to this), but get this ROL at their shareholders meeting seemed to indicate that a 32bit RISC OS was highly unlikely. As that meant ROL had *no* OS that *could* run a xScale class processor there surely was *no* point Castle approaching them for something they [ROL] hadn't got and had stated they [ROL] were likely not to have.
What RO5 has that *no other* version of ROS has is it runs on the very latest ARM hardware and has been hardware abstracted so it is no longer dependant on legacy chips or chips likely to become unavailable. Select does not even attempt to address this - and that is the real problem.
