We've already blown the whistle on several new projects that may be announced at Microsoft's Gamer's Day tomorrow, with "Ninja Blade" and "Lips"
being the most nebulous of the bunch. We still don't know what the former is, but 8Bit Joystick
has shared a couple of thoughts on the latter matter. The site states that "Lips" is, in fact, the codename for a new Xbox peripheral, and speculates that it could be a voice input device (karaoke microphone?) or some method of in-game voice recognition.
For now, we'll go with, "Hmm, intriguing." Let's hope Microsoft drops the balm tomorrow and fills us in on these ... e-lips ...
