The irony...
"Waitstation" but you're talking about Spring 2014. Nice response.
You ever think about this... if Sony drops in October they'll have more time to get more consoles in stores by the time MS drops the One? Diehard MS/XBox fans will wait for the One, but I'm sure people on the fence who just want to play 2K/Madden/COD aren't going to be thinking about Spring 2014 and Titanfall.
Once again. The consoles are already sold out regardless of release dates. Releasing first might get them a couple people who were unable to secure a preorder, but on the flip side the people who camp out and still miss it will make sure they get an Xbox one. And regardless of any of this both systems will be sold out this year, so none of it really matters.
And releasing early doesnt mean they will have more consoles available. According to pachter both started manufacturing around the same time and can produce about a million a month. Also rumors are pointing to Xbox having more units available at launch.
