If they stopped making 10 different versions of each MG kit then you might get some new ones
ver 1.5, ver ka, ver 2, ver OVA, ad nausium.
BTW there are 144 MG kits and only 124 1/144 HGUC, HG still has a bit of catching up to do
. And now it looks like they are going to give Wing a bit of a flogging so don't hold your breath for any Unicorn MG for a while
