There was no E3 sketchbook on Penny Arcade this year.
There needed not be an E3 sketchbook, because the webcomic geniuses at PA summed up the entire three and a half days in one simple comic.
And then they finished the job in their single E3 blog post:
No doubt the proprietors of Ladies’ Home Journal were breathless during Nintendo’s presentation, but those outside of that august body may derive less enjoyment. This is the deep-dish, delicious irony endured by the Nintendo stalwart: to see their platform of choice ascendant, even as their bright God turns his face away. Though it contained very little sustenance for our kind, the presentation was (as is typical) a confident, refined affair. The salvo was not a failure. It was simply aimed elsewhere.
That was E3 this year. More promises of future promises promising future promises and no real substance out of the big three.
