Full disclosure: I have an Xbox One pre-ordered.
I can see where you are coming from. If the news was something along the lines of "online play will NOT be ready for launch" I would be more worked up. That is concrete. But to hear that a company is having issues (as big as they may be) ahead of a product launch, and these issues may or may not be sorted out in time...I dunno. I have had experiences in the workplace where everything up to a product launch ended up being crazy, with just about everything that could go wrong going wrong, and yet the final product would end up executing just fine because we worked around the clock to get done what needed to get done regardless of the roadblocks.
I don't mind knowing these current issues but I'm not going to go out and cancel my pre-order. My guess is everyone at the Xbox division is working around the clock to make sure that these issues are resolved in time for launch. That may mean they end up being 100% resolved or only 25% resolved and it's a giant cluster F. My point is that I don't think the system should be judged based on this. I'll judge the system when it launches because that's when we'll know just how much of this is still an issue. And if it does turn out to be disastrous, which it very well could, I'll just return it.
Ended up writing a bit more than I meant to @_@.
