With all the talk about reprinting ASM volumes is it not remembered that Marvel has in fact reprinted Vol 2 before? It was reprinted in 2016 (2012 1st print), so in the terms of between Omni print runs really not that long ago, and Vol 3 came out a little over two years ago in 2017. Like Rimmer said it just isn't feasible for Marvel to keep everything in print at all times and I would imagine they can only slot so many books in the printers schedule. With the wave of reprints we are seeing happen now I think the powers that be have finally woken up to how big this market has grown and I would not be surprised to see most high profile OOP books get a reprint at some point in the future. It will just take time for the cycle to get around.
