I've only just started reading the manga, and I really wanna buy it all. I asked here before what I should get, and the new Viz translations seemed to be the main answer everyone was giving. That's the backstory, and that's all sorted.
The problem is, I only just recently found out that there are several arcs missing from this translation. Will Viz fix this? How long will it take, and am I better only reading it cronologically, and waiting for the R/S/E and LG/FR arcs to come out?
