The little change of this year's iPod lineup

The little change of this year's iPod lineup
Apple said "Let's talk iPod," recently .And this is the main topic .

Then what's the new feature of iPod in 2011 and what the little change in 2012?
iPod touch.Now it's white, it's 100 percent identical to the 2010 model. Seriously, after comparing the tech specs page from this year versus 2010, not one thing has changed. And the ipad is still with A5 processor,And the camera hasn't been changed either. It's still the poor camera same as the last year.Some one said that iPod touch would receive a 3G antenna upgrade turned out to be unture.
Ars Technica has questioned why the iPod touch hasn't been updated with the A5 processor when Apple went out of its way to laud iOS devices' potential as handheld gaming units during the latest event. I suspect it's a simpler motivator that their analysis suggests that trends in the overall handheld gaming market and among Apple's own sales figures are falling behind the iPod .
The A5 is reportedly very complex to build.
What is the "A5"? The A5 is a highly-integrated "system on a chip", designed by Apple, based on the same ARM architecture as the iPad, iPhone and iPod Touch. The A5 is dual-core, like most Intel Macs, but still runs at 1GHz, like the original, single-core A4 iPad processor. The A5 graphics engine has been updated, too; Apple claims it is "up to 9 times faster" than the original iPad's graphics hardware. We don't know yet how much memory the iPad 2 has, but to run the new iMovie app we expect it probably has 512 MB (like the iPhone 4, twice the original iPad's memory).
Production of the A6 processor for 2012's iPads and iPhones has reportedly already begun at TSMC, and the foundry's ability to produce that processor in bulk will likely determine the iPod touch's fate. If TSMC can produce the A6 fast enough to satisfy demand for all iOS devices, the iPod touch may see a substantial upgrade next year. Otherwise, it may only move to the A5 processor once the iPad 3 comes out featuring an A6 chip, thereby alleviating strain on A5 production. Either way, unless suppliers can step up their game production-wise, it seems clear the iPod touch will lag behind its more profitable brethren for some time to come.
There some other change about iPod:

• iPod nano:Only one change
• iPod shuffle:No changes
• iPod classic: No changes

Maybe th iPod will stick around for years to come .but its days of driving yearly innovation in the portable music player market are pretty much over.
In a word, the iPod donesn't make a big change, but with our eyes that it is changing much better and more useful.So we expect the new feature of iPod.
