because I couldn't find the piece-count on the first page I looked the new sets up on Amazon.de, here we go:
75001 (Republic vs. Sith Troopers): 63 pieces
75002 (AT-RT): 222 pc.
75003 (A-Wing): 177 pc.
75004 (Z-95 Headhunter): 373 pc.
75005 (Rancor Pit): 380 pc.
75012 (BARC Speeder): 226 pc.

btw, TRU (only in stores, not online) in Austria already has a 3-in-1 superpack featuring "The Battle of Hoth", "A-Wing" and either 7500 or 75001 (can't quite remember which) for 89.90 €
