Ok, seriously. Apple isn't going to include a new software on an older product (2nd gen iPod touches). I hope than you all don't think that Apple just makes these products as people order them, no, they have a pre-made group of them with the software that was available at the time they were released (OS 2.1.1).
When the new 3rd gen iPod touches come out they will include 3.0 because that is what is available at the time and so on...
You can't expect Apple to go through their entire line up of old unsold products to update them.
Yah, maybe they can put on a sticker that says, "includes OS 2.1.1" but that's basically like saying to the customers, "not the new operating system, don't buy this, wait for the new iPod touch".
