Sounds to me like they'll be releasing it at $170. The DS took a similar pricing route, with a price drop occurring first, then a hardware change at the same price as the hardware before it, without the older DS changing price either, but rather being silently discontinued, as far as I can tell.
I can't see what good Bluetooth could do for the PSP, though someone else may be able to tell me, but as far as I've always thought, Bluetooth is like a weaker, cheaper substitute to Wifi, mostly used so smaller devices can work wireless and still be pretty inexpensive, please correct me if I'm wrong, but wouldn't this feature be useless unless they were planning some sort of headset hardware, too? And if that were to happen, I suppose that means they plan to turn it into a phone, I would think.
To this extent, like a few people have said beforehand, making the device a download platform may be a better switch for Sony.
