I think the Pinnacle would do well in the current climate. It's only real fallback as far as I can see was the fact it was brought out approx. the same time as the awesome 710 Axis. Rather than pinnacle-ing as it may have done otherwise, it was instead eclipsed by the 710's HUGE popularity.
If they do bring it back, they should address a few minor glitches, such as putting Bronze-Phosphor washers on the pivot, ditch the re-curve blade for an easier to sharpen in the field straight edge and give that suckah tip up or tip down carry options. Oh yeah, using S30-V for the blade wouldn't be too shabby either. Given these changes, I believe the Pinnacle would be yet another success story for Benchmade. I would save my money to get hold of one if they re-introduced it as described.
All the best,
