There is still plenty of room in the other events (U/2000, Under 1600 and Under 1200), although there are size limits for these tournaments as well.
In terms of the strength of the fiels the Premier already has 11 GM's and 6 IM's. Once again there is a sizeable contingent from India, and it looks like some of the players who mplayed last year enjoyed the event so much they are coming back again.
