> This would be a bit different. Itanium, Sparc, Crusoe, ARM... all these CPUs were offering is the promise of better performance in some aspect.

Crusoe and ARM were not about the promise of better performance, but of being much more energy-efficient for the intended purpose (though since a few years ARM tries to get into a (more) high-performance field).

Energy efficiency kind of falls under the "performance" category. Just not raw MIPS performance but "performance per watt".

What I wanted to say is that the major selling point of RISC-V would be its open-ness rather than anything performance (or power) related. In that respect it has already captured the attention of interested parties, regardless of that the actual performance will be.
