Invest big $$ in APS-C for premier lens itself is questionable to me. Serious amateur will transfer to FF MILC if it comes one day.
Hmmm yes and no and maybe
Some will for sure, some won\'t because FF will come with extra cost, weight and size, particularly in the lenses.
It all depends how close the FF mirrorless will be to DSLR in cost/size/weight. FF DSLRs will always have the edge in performance because they are ~10 years ahead in development.
