Yes, in this context an equity stake would make much sense. A clear commitment to this project.

Well well, slowly we can wrap our heads around the script of this nice stage play.

For me it is also clear that the tasks of these three brilliant people (CLF, RN and JB) at AMD, to set a new strategy, new products, new marketing, was just at the beginning. So possibly AMD found that it needs "a little more" for AMD to restart and to compete e.g. with INTEL, and AM spotted POET for this project. A new, a big thing which will change the world of semiconductors.
In addition AMD would rise no competition issues with other potential partners (Google, Apple, Samsung, BAE). An interesting team, AMD, GF (IBM) and POET. Wow!

In this context also our recent private exchange of ideas about the fate of LS would be a peace of the puzzle which would perfectly fit.

Yes, POET is a great stage play, epic poetry, and we are sitting in the first row of its premiere!
To be seen soon in this theater!
