Not "my" interpretation... (I could not care less of what he'll do...)That is your pessimistic interpretation of what he said. I read it differently. In the end, it doesn't really matter. If an update comes out, great. If not, oh well. Plenty of other games to entertain.
It's just what he said (actually wrote)...
He did not promise anything to anyone; only that he will not abandon his game (my interpretation = he will not drop the digital rights of his creation, even if he drops the project...)
