Dash, given what we've heard from management over the past 6 or 8 months, I think POET has likely hit a couple of snags that they didn't see coming back then.  Is the main issue the lack of access to wafers?  Hopefully, as that apparently has been successfully addressed.  I know nothing technical about the tech, but other things suggest some issues, and I'm also hopeful those issues merely boil down to delays of reasonable duration (as in, get it optimized before something else comes along).
