The new 2008 TECHNIC sets, are now available from S@H US for pre-order (shipping by 2.Jan). Soon they should appear on the European counterpart.
The surprise was for the 'Power Functions Battery Box' sold as set number 8881, to feed more power to your creations (each Power Box can drive 2 XL-Motors, or 4 M-Motors simultaneously).
So, guess the motor and/or IR receivers will follow shortly as well as the promised PF/9V conversion cable.
Rest eagerly waiting to see, if LEGO will bring us a kit with PF elements and a few additional parts, like it was made available for years with all former TECHNIC motors (Hopefully for the next September season...).
Meanwhile, also some pictures for the LEGO proposed B-models.
