Probably not, but Microsoft is going to need to change direction fast to counter the flow of news/marketing. Because there's a lot
of room for really aggressive advertising on Sony's part here. Their product launch, at this stage, is just so much stronger.
Assuming they can keep control of their momentum, and start (and manage) the drive for holiday gift guides, tech reviews, etc., they're going to be in a REALLY strong place this holiday season.
E3 is realistically more of a press event than anything else. I know gaming culture doesn't really treat it that way, but it is. Two of the top-five articles on Forbes right now are about the PS4. Many, MANY people outside of the gamer population were watching E3 yesterday. Microsoft's stock fell when they released their price point (which is above what analysts were predicting). That's never something you want to see following a major press presentation. This was an event purely to drive hype and excitement.
Now, the news is about how they failed to whelm audiences, and not about their product. That has a far larger reach overall than the gaming-specific information.
Side news that will still probably be welcome to some people: Kotaku is reporting that the PS4 is region-free.
Also worth noting: people I'm friends with on Facebook, who I had no clue played video games at all, and even now bet they aren't major consumers of gaming news at all, are coming out of the woodwork to express their excitement for the PS4 (KH3 in particular). Because they're hearing about it over social media, and going to check it out. Between Tumblr, Twitter, and Facebook, it's a pretty wide reach.
