I sure hope that you’re not pulling my leg.
If is comes as an upgrade to the iMac that I already have, I’ll but it in a heartbeat.
If I have to buy a new system to get it... I’ll do without. I already own too many computers. ;>)
I have no insider knowledge. I do know that Apple will not release it until it's ready. Whether that is this coming week or seven years from now only time will tell.
