The case seems less of a good idea with the cost of different production runs and I'd execpt an even more limited appeal to what I want.
I am talking about a VIC version, which I do understand, as Retrobike points out, is highly unlikely due to it's small target audience. Perhaps a very tiny little bit more likely is a bootable option to have a VIC mode as a later upgrade.
I'm not hopeful, but it's what would make me bite. Whilst I can see this is desirable I don't have enough history with a C64 to tip me over the edge.
