Pics of the new Gallardo LP560-4 are now online, and I think it looks amazing.
Obviously, the front bumper is inspired by the Reventon and the tail lights are based on the ones on the Miura concept (which the Reventon's were also based on). Other changes include the headlights, a solid rear grill, new exhaust tips, rims, and engine bay. The engine has been bumped to a 5.2L V10 (from a 5.0L V12) producing 560 HP, and weight has been reduced by 44 lbs from the regular Gallardo (it's still heavier than the Superleggera).
Hopefully, they will make a spyder version someday soon.
