Despite all the kissing and making up between ROL and Castle, it seems pretty clear that we have a forked OS still, and little real prospect of that changing in the near future. ROL's stance seems to be to support any plausible competitor of Castle's: first VRPC, now the A9. If ROL really wanted to embrace Iyonix owners there are plenty of good commercial reasons to justify that: owner base, modern hardware, and scope for development being 3 of them. The A9 is splendid and I wish it well, but it has 3 years' of sales to make to catch up with the Iyonix and that is not going to happen quickly, if ever. What is needed is a situation where future Iyonix buyers can opt either for RO5 or Select-for-Iyonix: if the latter is superior, as it may well be, most purchasers will choose it, and existing owners will upgrade. A unified OS will then have been achieved, and much future time and energy duplication saved.
