I think it is probably the most likely scenario. More likely than grandfathering. This is after all what they did with 400k and 65k proof. They are not going to grandfather the requirement for criminal record check or insurance if these are applied, so how can they grandfather only the money? They could perhaps but you would still be required to furnish other requirements. THEY DON'T CARE and neither does it seem, do our embassies.
I reiterate, when Hapkarn said it was "too easy", IMO he clearly meant that to just be over 50 and meet financial requirements was not enough.
