Seeing as we didn't have an E3 thread, I thought I'd start one.
So, some interesting news comming out of Microsoft's press conferance: It looks like they've copied Sony, by copying Nintendo. Blades in the XBox 360 interface will now be known as "channels" and, the much-rumored avatar system has been revealed, and the avatars bear a disturbingly familiar appearance. That's not to say all of Microsoft's new ideas came from Nintendo, they're also copying the EyeToy. I must say though, I do like the greater customization options for the wannabiis (or whatever cute name the Internet has come up with for them already). This is what Nintendo should have done with the Miis since the beginning.
On the Nintendo side of things, it looks like there's going to be a new attachment for the Wiimote that will improve the pointer functionality. I find it odd that they'd release an attachment just to improve existing functionality; they could just build the improved pointer function into new Wiimotes, so there must be something more to it. I guess we'll find out more tomorrow.
