You've listed a lot of stuff for Sony that has been CONFIRMED TO NOT BE APPEARING AT E3
I'd say Sony based on your list, but since it lists stuff that won't be there...after deducting the stuff that definately won't be there then I'd say...
Microsoft
...Nothing special from them though really, unless that 3d dashboard gets released during E3...Prolly just an announcment for the "fall update"...
