MineCon will return in 2012, though it won't be held in its previous Las Vegas digs. Mojang director of fun (seriously her title) Lydia Winters took to the company's blog and cursorily detailed the next MineCon as taking place in "a secret location" somewhere in Europe. Winters promised "ALL the details" as soon as Mojang signs the lease for its Europe-based convention.
Additionally, Winters confirmed that Mojang will indeed be attending PAX Prime once more this August/September, though she didn't say what those Minecrafty folks will be showing off. We've got high hopes of seeing the next big update to Minecraft Xbox 360 Edition, and we suspect that 0x10c may also be in attendance.
