Sony should stick to the long game. Last gen it was laying the groundwork to repair the PlayStation brand after the missteps of the PS3 launch. They lost alot of marketshare to MS. They've built up their first party studios and set expectation for quality (they've got to maintain that this gen). They've got some compelling services and differentiators. This gen is about eroding MS's marketshare by competing neck-and-neck in the US, strengthening their studios and offerings, and padding the reserves. I don't think Sony sees this gen as a means of dealing a deathblow to MS. They proved the rest of the world was theirs last gen; so being neck and neck with MS in the US is gained ground. MS is on their heels; so for Sony why not let MS bleed to compete.
MS is doing what they have to do in the short term. They need the same approach Sony took with the PS3...knowing that this generation is lost to them sales-wise, but that they can make efforts to improve their brand. Some part of that has to contain a strategy of getting WW support; otherwise they'll find themselves in a similar situation at the start of the next generation (possibly with a stronger, more aggressive Sony).
I think both companies have learned a lot about the market this gen; had some things reaffirmed and had some beliefs tested and shattered. While there's still a lot of time left in this gen, I think we know the trajectory of things at this point. I'll be looking at this gen to see how serious MS takes this industry. There are virtually no pathways to victory, so I think this gen must be seen as an investment in the next. When XB1 peaks and as the competition gets stronger; will they still invest in year 4,5, on up? How long does the 'all about the games' strategy last? In Sony's case, they've got to execute on what they've done in the past (no more Driveclub or LBP3 fiascos), strengthen PSN infrastructure, take note of MS's cornered strategy, cause its likely they'll see it again.
