Notch has made the decision to put 0x10c on hold. However, the community plan to soldier on in Notch's absence with Project Trillek.
US Gamer reports:
In case you're still elbows-deep in Minecraft and have yet to hear about Notch's new undertaking, 0x10c is a sandbox science-fiction game set in a universe where the space race never ended. It's not a particularly jovial environment - massive black holes and dying stars abound here - but it does have a fully functioning emulated 16bit CPU, one many have become utterly fascinated with.
"I think the main reason we set out to do the project is that we were really excited for 0x10c." Nouht, who initially broke the news of Notch's seeming loss of ambition, explained. "As soon as Notch said he was dropping it, a lot of the community were disappointed. Hearing Notch say there wasn't going to be a 0x10c on the livestream really shook people up."
Shane Dalton, who serves as Project Lead and head writer the community-run endeavor, has little to say about 0x10c being shelved. "I think we didn't really look into why he put it on hold. We just sort of looked at the project and were like, 'Okay. This is a community project now.' We're not using any of his old code, his name or anything."
