Lua 5.1 or 5.2?

[Ketho]

I know /run, /script and addons are not yet available for use in order to print _VERSION, but does anyone know if Blizzard said anything yet about updating to Lua 5.2?

Lua 5.2 has been released since December 2011, and maybe it would help a lot for addon authors to anticipate on it if Blizzard were to update it in MoP
