A translated version of Comprehensive Tovarisch! That series is seriously underrated and I'd love to show my non-Japanese-understanding friends a version they can actually read instead of standing over their shoulder while they're reading my physical copy and trying to explain what's happening. Seriously.
Other than that, I agree with the current list you've got up there. Strike Witches' (officially translated) manga spinoffs are going to be released next summer too, and upon hearing that news I immediately had to preorder. Had to.
And if I were to add anything else, it'd probably be everything in my subscribed list, aha. Things like Riko & Haru & Irukawa Hot Springs, Bousou Girls-teki Mousou Renaiteki Suteki Project (B.G.M.R.S.P.), A-Channel, Sakura Trick, Saki, Hayate x Blade, Yuyushiki, Yuru Yuri, Aiura, and such. Did I mention Sakura Trick yet? And Saki?
But what I'm really looking forward to is the future releases in store. Onwards, 2014!
