A7 has some features I want but unlike A6 it's current state is too unfinished. The aim is to complete and release a project that is stable. A7 has even yet released working templates that are on the 'do list' whereas they are working in A6. Once these are released and bug free I think A7 would be a practical switch but until I see working templates and a working engine without half complete promised features (RPG template as an example) it makes no sense to me to switch.
Everything that's holding up the release Intense X is holding up my switch as well. I don't want to be 'on hold' for months waiting with baited breath for a 'workable' release. I need that now. A6 has that. A7 doesn't.
