In a very brief announcement today (consisting of nothing more than a single line of script, a flash of the logo and a few people walking past with Creeper masks covering their heads), Sony confirmed during their Gamescon press announcement that Minecraft will get an official port for the Playstation 4.
Following the announcement, creator Markus "Notch" Persson took to Twitter to confirm the game will be heading to the PS4, but additionally confirmed PS3 and Vita ports as well:

No other details are known so far, but the announcement goes against long-standing beliefs that console Minecraft would remain XBox-exclusive.
