Right. And the one after that will have the XQX76 chip. And I heard the one after that will have a built in Espresso machine. There will ALWAYS be the next big thing. And that article doesn't even say WHEN it will be out. What will the new chip be able to do that you can't do now? I guess what I'm saying is, if it's real important to you that you be the first one on your street with the new chip, then wait and get it as soon as it's out. It's a personal choice. For me, it's easier to upgrade when I'm due. Sure, I may get the A5 chip a few months later than I could have, but it's not like I'll be stuck with a Motorola StarTac for those months. The phone I have now does everything I need it to. The added stress of constantly chasing the next big thing just isn't worth it to me.
For instance... I bought a new phone shortly after the 1st iPhone came out. Lots of people told me I was stupid, that the iPhone for Verizon would be out announced any time. Then I bought my LG EnV. And people told me the EnV2 would be out any day. Next was the Droid, I got that pretty soon after it came out. But when I bought it, there was already talk of the Droid 2. When I bought the iPhone, I had people telling me the iPhone 5 would soon be out. Or maybe I should have waited for the Droid Bionic. In technology, there will always be something new on the horizon. The next big thing will only be the next big thing for a few days until another big thing comes out. I've found it much less stressful to be concerned with having something that works for me NOW. ;-) If the 5 comes out and it's life changing, sell the 4 and buy a 5, or hang with the 4 for a few months and then get the 5. Think of it this way, if you don't buy the iPhone 4, you're stuck with what you have for the next X months til the 5 comes. If you do buy the iPhone 4, and the iPhone 5 comes out this summer, the worst case scenario is that you'll be stuck with an iPhone 4. Not the worst thing in the world, it seems like a fine phone.
YMMV.
