the same qs was mine.
From various sorces of which some were quite reliable what i got to know was that either the new generation will be skipped or it will be sometime launched at the end of 2016.
so i just booked my aspire PT and got it 15 days back after waiting for a month. trust me its amazing .
Things THAT "I" considered while making decision
1) why would they launch when the sales are quite decent for the facelift model.
2) why would they launch the new model until they make much more profits to compensate for the facelift model being offered at the old price.
3) the new model to be launched would require huge initial investment and to recover that i am sure the same price range would not be offered.
