They said it'll cost depending on how much select you've subscribed to. Hopefully current select subscribers will get them at an appropriate margin over cost. What I wonder is will this be on the premise that you return your old roms.
My biggest niggle with softloading isn't the loss of RAM, it's the fact that I have to wait for the hard disc to mount twice (i.e. boot then reboot into select).
On a select features note, I wonder if they're planning to fix cut and paste in writeable icons. I mean, at the moment it's against the style guide and most other programs. I did report it but unfortunately there's no bug tracking thing.
