Blues, here is what I see on that CB EOL page , but of course the one has an asterisk, so may be a model like mine extended, which may amount to that same d*MN thing:

"Chromebook 315 (CB315-2H, CB315-2HT) Jun 2029*
Chromebook 315 (CB315-3H, CB315-3HT) Jun 2029
Chromebook 315 (CB315-4H, CB315-4HT) Jun 2031
Chromebook 315 (CB315-5H, CB315-5HT) Jun 2033"

I guess that I'd have to look at the tag on the bottom and see when these were issued, since the specific model is not shown, but when copied that on Amazon, they show recently released.
