Do you think that porting Minecraft to Xbox 360 and Xperia is a step in the wrong direction for the game?

Now, it has been shown that Minecraft will soon be released for the Xperia and there has also been news at E3 that it will be ported to Xbox. Personally, I think the gameplay would be to clunky for the Xperia. You also wouldn't be able to do everything on Minecraft for Xbox and Xperia as you can do on the computer: Multiplayer typing commands and simple ease of accesablility to the menus and features of the game. So what do you guys think? Is this a step backwards, forwards, or did it not hurt or help the game at all. Personally I think it's a step backwards. Why spend all this time porting it when you could be putting out updates that will keep the current fanbase interested and porting when the game gets officially released?
