While these are interesting numbers, I'm not sure they're as telling as you might think. Sony's numbers are impressive, but don't underestimate the effect of a $100 price difference, something Microsoft will almost certainly chip away at by the end of the year. Likewise, Titanfall IS the kind of flagship title that sells consoles. The very fact that there are people mentioning stuff like Naughty Dog and Sucker Punch in this thread are examples of folks who'll follow certain studios and who sell consoles. TItanfall is such a release. Will it be enough to MS dominance in the market? Very unlikely.
But here's the thing all these articles seem to forget: it isn't 1989. It is far less likely for a console manufacturer to drive another out of business in this market. Nintendo has lost 3 out of the last 4 console releases in terms of numbers...but they never lost money. The Wii U is never going to match the Wii's sales numbers, but it will likely follow the Gamecube into profitability without market dominance. The PS3 and Xbox 360 eventually plateaued against each other, sharing most titles. The PS4 and Xbox One are slated to repeat that exercise....meaning only the exclusives will matter, eventually.
Honestly, Titanfall is the first thing about the Xbox One that has me considering a purchase of either console. The PS4 sounds all good and well, but my PS3 soured me on Sony's online execution. The 360 and PS3 also still have plenty of games I haven't gotten to (Hello, Last of Us, Bioshock Infinite and others), which makes it hard to justify purchasing a new console...especially when I know they simply won't support some of the video features I'd like, yet (and possibly ever).
