The first developer preview apparently has the same requirements as Mountain Lion. If you are a developer, the info should be available here:

You should not be discussing anything about a not yet released OS in an open forum as you are violating your NDA - if you have a legitimate copy as a developer, you should be asking your question in the forums provided for you.

You should be able to since you have lion or later, but apple has not told us anything about that yet.
Running a certain OS is no assurance that a newer OS will support that particular hardware. There are machines in use today which support Lion, but not Mountain Lion.

Good news, your imac is indeed supported and if you didnt already know is a free upgrade from the app store.
As far as support, since your iMac is more than 3 years I would consider yourself luck that apple is including old hardware apart of there update. That being said, I just purchased a new iMac (27inch) and compared to my 2011 Macbook Pro, it OMGWTFBBQ fast. I would recommend highly that you invest into new hardware, not only would you be getting a brand new refreshed iMac for 2013 but you would enjoy a better overall experience with the new operating system.
Also if you buy a new Mac, iWorks is included for free.
