If you follow the media enough, you'll always notice a certain amount of bias regarding E3. Everyone has their favorite console grandaddy they want to succeed. To hear Microsoft fans tell it, Microsoft won. The same can be said for Sony or Nintendo.
A fairer assessment would be to say that E3 was really more of the usual this year. All the introductions to technology both old and new should seem a bit familiar to any avid viewer. The last time anything major happened at E3 was when Nintendo put a knife in the ice box that HAD been motion gaming with the unveiling of the original Wii. Although, even that had its stagnant phase.
Something that happened with E3 this year that was of particular interest to me was that almost every single company at the expo was showcasing at least one iOS game. Admittedly, most of them are not worth much more than a random bejeweled style pop cap game released in 2005 featuring forgettable characters and menu items that have nothing to do with the game itself.
Even so, just about everyone owns at least one iOS device these days, and it's safer to apply games to a platform everyone already has than to go out on a limb and hope the fans follow.
Some of the bigger triple A titles showcased at E3 seemed impressive graphically. BioWare is still kicking this year with Dragon Age: Inquisition and the ever continuing PC-Only saga of Star Wars: The Old Republic. Both titles are sporting interesting visual designs; the artists have really outdone themselves. From Batman Arkham Knight to The Witcher 3, this year and the next one are liable to be a great time for Xbox and PS4 owners.
E3 also had it's share of disappointments. Some of the games showcased weren't even in an operational state. They were only vague demos which seemed to sport a ton of aesthetics and bugs, but none of the game play you'll see in the final product. Any E3 goer is used to this by now, but it's a problem that developers need to quit adding to.
All that aside, Nintendo seems to be doing better this year. They're taking risks, and it seems to be paying off for them. I was interested when I heard they were going to show a video presentation as opposed to a real press conference. In my mind it works great, and really shows that Nintendo is the biggest grandaddy gaming is likely to see at E3. Ever.
