Really best bet is to go ahead with original plan.
Some people will actually lose their entire character if it gets rolled back the extra few weeks.
For the new player's sake (as in keeping them) - the 20th is probably the safest bet imo.
I'd rather keep 50 new players than give 100 vets some gear back, its easily reattainable whereas for a new player who's spent 40+ hrs killing rats and mutants - he/she will just go elsewhere.
Of course my own opinion.
