Mojang CEO Carl Manneh has said three unannounced projects are in the works at the firm, two of which will possibly be announced or even released during the first half of 2012.
"What it is today, I don't think he knows himself," said Manneh. "We certainly don't. It's probably going to be a lot of testing and playing around to see what works."
Manneh said the other two projects will help establish Mojang as a brand, and help the firm get away from a perceived reliance on Notch.
"I think Notch will always be the fixed star over a long period of time, because he's Notch," he said. "But we don't look at it that way - he gets a lot of attention, but other people in the company do too. So it's not something we're actively concerned about.
"I think that comes with the new games we're creating. They will have a big impact on Mojang over the next year. I can't talk about them, because we have NDAs with companies."
Mojang wold like to be "very transparent" with the public regarding its current development slate, said Manneh, but "in this case we can't."
