We’d heard rumors that the iPhone 3GS would be getting fast 802.11n Wi-Fi to go along with that S for Speed, but that never panned out — except for the new third generation iPod touch.
iFixit has been doing their prerequisite tear-down of the brand new device, and MacRumors says:
One of the more intriguing differences uncovered so far is the inclusion of a Broadcom BCM4329 combination Wi-Fi/Bluetooth chip, which supports the 802.11n Wi-Fi standard in addition to 802.11a/b/g standards. The iPhone 3GS and the second-generation iPod touch utilize a different BCM4325 chip, which supports only the 802.11a/b/g standards. While Apple has apparently not activated 802.11n capability in the iPod touch and it is unknown whether it will choose to do so in the future, the new iPod touch hardware does appear to be capable of supporting the standard.
Speaking of rumored-but-not-delivered:
iFixit has also revealed that there is a small empty space at the top of the device (approximately 6 mm x 6 mm x 3 mm) where an iPod nano-style camera could fit. The iPod touch does not appear to be thick enough to adequately house an autofocus camera as found in the iPhone 3GS.
Would we have wanted an iPod touch with VGA video like the nano, but no 3mp stills like the iPhone 3GS?

Did Apple plan to add a camera to the third generation iPod touch — just like the iPhone 3GS and iPod nano — but pull it roughly a month ago due to technical difficulties? We heard that rumor last week, after months of previous rumors and leaks that made the camera seem all but a certainty.
For his part, Steve Jobs said Apple prioritized lowering prices over adding new hardware features.
Now, AppleInsider is merging those two story lines into one consistent, and not incredible report. Sourcing people familiar with the matter (PFWTM), those familiar with the situation (TFWTS), and others familiar with the situation (OFWTS), Apple initially decided to add the cameras to the iPod touch feature set only to discover issues with the camera sensors they received. So, Apple execs made the call to yank the cameras last month. However, Apple still wants to add the cameras back in to the hardware, and could do it at any time, and at the same price point.
Obviously, not announcing new iPod touches before the holidays, or announcing that newer ones might show up at some point (who knows — maybe not even Apple yet — when exactly), were not options, so they went with the beefier internals at 32GB and 64GB.
Wether that’s the real, or even approaching real, story or not, likely only a few folks high atop Apple know for sure, but it does make a modicum of sense (even if well seasoned with salt grains).
