Right here we go ,the Lvl7 you refer to is the last and current FACTORY Automag all new Mags are supplied as Lvl 7(and have been for years
what no development ).
The Lvl 10(don't know why its called that) is an aftermarket AGD upgrade that will fit on all Mags Lvl 6 upwards(don't ask!) and all R\T valves and does what Billy and T\L says.
There are as yet no plans to release Automags and R\T's with the Lvl10 conversion fitted as std,well not by AGD but AGD\E are thinking about something along those lines in the near future.
Crap bit of marketing as the Lvl10 transforms the Automag and R\T's into a very capable marker but they won't fit `em in new markers as std.
