Kap,

I don't think they need to go beyond the 9-issue superscalar.

I once did performance analysis on a 4-issue processor, and discovered that the second slot gets about 50% utilization, the third slot gets about 5%, and the fourth gets about 0.1% utilization.

Also, given that only about one instruction gets retired per cycle, your assertion seems pretty darn safe.
