I've an early to mid 2009 24inch iMac currently running Snow Leopard (all system updates installed to date).
Do I need to install Lion before installing Mountain Lion?

Thanks.No. You can download the developer preview, make yourself a recovery USB stick by "restoring" InstallESD.dmg to an 8 gig or larger USB stick formatted HFS+/GUID partition scheme, then boot to that stick by holding ctrl to install ML. I upgraded SL to ML using this method on my test machine and it worked just fine.
BTW, if you redeem a code for ML and the download fails b/c you aren't on a supported machine, don't panic. Simply log in to the app store on a supported Mac and download ML from "purchased items."
Thanks.
So currently, it is possible to go from SL to the Developer Preview of ML.
Is it known if it will be possible to go from SL to the commercial release of ML, "late summer"?
Is it possible that Apple might enforce a higher purchase price for SL users, via the App Store checking what version you currently have?
