I'd say Sony had best overall content and flow, but was missing any news that really created a stir...
While MS to me only really had news that created a stir...
And Nintendo had almost nothing... but then they didn't need to have anything frankly as E3 I would argue means nothing to Nintendo with their current Wii/DS sales and massive adoption by a broad range of general gamers
Try to be reasonable... its easier than you think...
