Winter '09 / '10 - Too Much...Too Soon?

How much longer can the current flow regime support 'Nor-easters R-Us'?

Full-latitide mean trof axis INVOF 80°W
Bagginess @5H
Cyclogenesis off the SE coast
Crashing AO currently @-2.535 (-4.87 index delta past 30 days)

All good things must come to an end...to coin phrase. Forecasters must always face facts...flow regimes don/t last forever.

What are the realistic chances the current pattern continues deep into winter?  Is this too much...too soon?
