My guess, and I could be a million miles off, is that Bungie will change the little yellow number from 1060 to 1360 and the exact same weapons with the magic new number will start to drop. Call me crazy.
Or you could be right on target. Bad Omens, Gnawing Hunger, Ikelos weapons, reissues from the recaster, ect already prove your theory to be a viable one.
Expecting bungie to drop 500-600 new weapons to replace the old is just unreasonable. It makes sense that they brought some stuff back
No, sunsetting 400+ weapons just to bring them back again is unreasonable. What is the point? Makes the whole thing redundant
