I want to care...
... I really do. I'm a professional iOS developer. I'm about to change jobs from one that provides a phone to one that doesn't so will have to buy my own for the first time in about half a decade. But I think my problem is this: if I decide to stick with an iOS phone for work then there really aren't any options. So what's there to get excited about? Whatever they release is whatever I'll get so I don't really need to know anything much about it in advance; I'll figure it out when I open the box. Conversely, if I decide iOS isn't essential then I probably won't consider the iPhone at all, as phones are all pretty much the same so why buy one of the more expensive ones? A Motorola or a Nokia will do, no need for an Apple or an HTC.
So, short of announcing either that iOS is going to be available on other phones or is no longer going to be available on the iPhone, there's really nothing they're likely to say that will affect my buying decision.
