If this new 450 Marlin is the heir apparent, then sooner or later, the factories are going to stop loading for the ancient 45-70 G. This will happen in small steps, but only the weakest bullet designs will be left.
I wouldn't bet the farm on that happening.
IMHO, the .45-70 G will outlast the .450 Marlin, that is if one or the other goes away.
