FWIW, there's now this as well:
Bridgestone Potenza S007A
It likely won't match the Michelin Pilot Sport 4S for wet grip or NVH, but it stands a good chance of beating it for dry grip and feel. It's 2 lbs heavier than the Michelin, but still 3 lbs lighter than the OE tire. Could be a great call for an R3 that doesn't see much rain.
