Sad sad news!
Sad for the team, they put a lot of effort into this, I'm sure they made a lot of sacrifices for that project, and it's never pleasant to end an intense effort like that.
And of course sad for the customers, who were counting on them. Especially since Helios was a success, customers were had high expectations for Helios64. Very sad that it didn't work out...
I believe hardware wise, the team did an excellent job, Helios64 looks really good, and the specs were quite nice.
But I'm guessing it's on the software side that it didn't work out, which is really a shame, because software can always be fixed. It requires time, it requires effort, it's not cheap, but it's easier to fix than a hardware issue.
So although I'm a gutted that they are pulling the plug, good luck to Kobol team, and hope that you come back having learnt from this experience
