IMO, An industry-wide TPI will never happen for alot of reasons, mostly that it isn't in the interest of whichever company has fallen behind. Intel, especially, likes to control benchmark tests and would not officially endorse a benchmark unless it could have *at least* the sort of control it (is speculated to) have had on some others. For them, it would almost be like outsourcing its PR to AMD and vice versa.
Hell, I don't even think AMD and IBM could agree on a TPI scheme and they're not direct competitors.
