Microsoft: 2 - If most of it wasn't leaked or was the second E3 they have shown it would of been much higher, plus some of their better games suffered from horrid presentation, for example Sunset Overdive is a game I will probably get but how they presented it was bad.
EA: 2 - I haven't really been enamored with them for awhile now. And their shows don't even need to be leaked speaks how predictable they are.
Ubisoft: 2 - Suffered from the same problems as Microsoft and Sony, whould be a little lower if decimals where involved.
Sony: 2 - Same as Microsoft above.
Nintendo: 4 - If decimals were allowed it would be lower but. They came with what was expected came with some surprises. Surprised me with how close the Amiibo "platform" was to my fanboy fantasies. Plus the "leak" time has had almost now effect on the show since none of Miyamoto's games where really covered in the conference. This is what they should of done last year.
