But they said they haven't been able to finish testing it due to time / resources... they said that in both announcements. Can't lie about that in a market release.

To me, when they have an answer they'll tell us (based purely on the fact they mentioned it at all).

i understood they made a few variations of the chip in the PL4 so maybe they've got a couple that have given results and a couple that are still going...? Hence the "tuneable" comment.

maybe they don't want to say anything because the clock is still running, and the longer it runs the better for demonstrating the potential of the solution.

i mean that doesn't sound impossible, does it?
