Actually latest word from Tom is that level 10 will become standard soon on all E-mags, RT's and retro-valves. New retrovalves and valves on the RT's and E-mags will be the 3 oz lighter aluminum X-valves.
As far as I know basic mags will still be level 7.
As far as what AGD has in store for the regular mag, they are working on milling ideas for a new all aluminum mainbody that takes Angel vert feeds and Cocker barrels. The main thing is, AGD wants to make parts that will retro-fit any mag out there so current classic mag owners are'nt left with no where to go.
