If you go even further back you will see even more announcements of milestones that were never met.
Timelines are expectations, and history shows that for GMC these are best-case expectations, which is why they are hardly met.
The quarterly report should be out soon - I'm very interested to see how much cash they actually have left in the kitty. Hopefully it also contains information about the next set of imminent milestones.
