I have no doubt that they'll make that money back on the Merchandising. The game iteself isn't going anywhere and will probably continue to sell, but the merchandise will branch out and be the main money bank.

In terms of Minecraft 2? Don't know really where it can go. It is essentially Lego and I'm sure you can build anything you want in the game so long as you can devote the time to it. Not too sure where you can go from "Here kid, go nuts and build what you want". I believe their will be a Minecraft 2 after this news, just don't know what it will bring to the table.
