Thanks.

I suspected that learning C-Script would be the safest option and gathered that it would still be around in early versions of A7...

Just didn't want to learn something only to find out that C-Script wouldn't be supported for very long and most of the 'newer features' would be implimented into Lite-C rather than C-Script. Or to find out that Lite-C was coming to A6 anyway (Is it?). Oh well.
