iPhone 2.0: Spidey Sense to Tingle?

Confession: I haven't listened to FM radio since... well, since I got my iPhone, but it seems FM isn't just for Top 40 any more. 9 to 5 Mac, which found more details on the previously mentioned Broadcom BCM4329 wireless chip, which could include:

the ability to receive and send (the previous model could only receive) information through FM radio signals which theoretically could be used to broadcast sound into car stereos..without external adapters. It could also be used to pick up FM radio music, news and sports broadcasts on their iPhones and even, in August, on iPods. Currently the FM reciever is only used to pick up communications from the Nike+ peripheral.

Of course, just because the chip supports it, doesn't mean Apple will surface that support, or use it for anything other than what it already does (like Nike+).

But here's the thing: are the rumors flying just a little too fast and too far now? Are we really going to get everything and a bag of quad-core chips in the next iPhone hardware release, or are we -- as per standard internet protocols -- just hyping ourselves up for massive disappointment come June?
