I know I am. It's a personality defect, but everyone has some, right?
Listen, I'm not too sure Microsoft's on their way to making money any time soon. Sure they posted a profitable quarter, but how many more Halos do they have on the back burner? The thing is while they made >300 million sales in the first week of Halo3 (a large portion of which I'm sure turns directly into profit), they still only posted quarterly profits of 150 million. As in to say that without Halo (which will be the norm for almost all forthcoming quarters) they would have conservatively lost 150 million dollars. After 2 years and 3 billion dollars (1 billion of which was due to a combination of design flaws), they're still not at a level of sustainable profitability on 360.
Even if they were wildly profitable going forward, I think they could only hope to break even on 360 under the most positive scenario. That still leaves them 4 billion in the hole due to the first machine after 10 years on the market. If they don't make massive market penetration with the time 360 has left (and it seems moderately clear that won't happen in Japan or EU territories) then any investor/analyst/shareholder in their right mind would say further spending is probably good money after bad. Don't forget, they posted their first quarterly on the division after the Halo2. It didn't help their financial situation in the slightest.
I'd also suggest they're probably reconsidering their illusions of dominating the living room media space. 360 clearly isn't penetrating beyond the traditional markets, Nintendo (whom they ignored) seems to be doing a better job of being accepted in new markets, and their ultimate objective of at least blocking Sony (if not displacing them) has been achieved. They could drop out now at least happy in the knowledge PS3 won't encroach on the PC space.
As for Sony, well, they've basically inverted. Playstation used to buoy the rest of the loss making divisions up, but now it's the other way around. Their momentum is lost and their economics are built on domination which is built on sustained momentum. They're no Microsoft and certainly can't sustain 2 billion yearly losses for more than a year or two. Not conscionably anyway. And that becomes a legal issue. The board of a company has a legal obligation to do what's in the best financial interests of their shareholders. If it looks like there's no way something of the best possible value is going to be gained then there's a legal obligation to discontinue that negative business. Sony can look to the possibility of strategic advantages and future profits on PS3 for the moment, but not for much longer if this state continues.
@ elendar They have failed over and over. It doesn't matter if the industry sees 13 billion dollars annually if the collective development cost is 20 billion. Of course you're right about the merging of the markets. They'll keep trying, but I think video games have failed for them too badly to remain their avenue of choice much longer.
