Rare at this time....but who knows what they will be like once they start getting some mileage on them. A few more years will tell us a lot. Only sure thing is yes, go with a 2009+ (987.2) to avoid the IMS altogether.

I think those Rambo bearings will outlast most of m97 engines. While any sealed bearing inside an engine without a direct oil feed does not address the issue of oil starvation and contamination, if you make the bearing tough enough it will stay together long enough for something else to go fist that takes down the engine.
