"So, when can we see a 32 bit RISC OS 6 for the RiscPC? This comes with huge benefits at the cost of not running antique software; and nobody would be forced to upgrade, anyway."
Personally, I cannot see any benefit of this to the Risc PC user. The downfall of a 32bit RISC OS 6 on a Risc PC is that all the 26bit software that people still use will no longer work, other than running slower under Aemulor.
I'm sure if lots of people get in touch with ROL and and say they want to run a 32bit version of RISC OS 6 on their Risc PC, then they would make it available.
