Hmm, do you have a link? Because I watched a interview from IGN where they asked a dev that same question and he answered ''We do plan on introducing some sort of communication features'' but w/o confirming voice chat. Right before this sentence he explained that thx to the gamepad, you can at all time see where are you allies and what they are doing so you can figure out on your own what to do. Basicaly my translation would be ''We know this is not the answer that your viewers want to hear so we won't give you a straight ''no'', but we will give you a explanation(excuse) on why it won't support it even tho the real reasons is that here at Nintendo we are too uptight when it comes to online''.

Here's the link http://ca.ign.com/videos/2014/06/11/splatoon-gameplay-demo-ign-live-e3-2014 the question come at 4:10. But I would loooove to see voice chat in that game, so if you could send me a link to where you heard this it would be appreciated.

I heard that one of them said it's the best way to play the game.  I assume you use the gyro to do those quick movements and the right stick for precision. 

This might very well be true, but as I already mentioned I played it  less ideal circumstances and to me the controls felt awkward.

You may find this helpful in relation to controls
