Perhaps you're right. Just seems odd that they'd implement it a month before ivy bridge processors are available. If the iPad's ability to take advantage of it wasn't a consideration at all, you'd think might have waited to implement the feature into the OS until a time that was closer to at least the release of the processors they'd be using. I get the argument about them not wanting to advertise it, but I think that's more or less to make it a bit more triumphant when and if they trot out macs with the technology.
Just to try and get some aspects of your assertions verified, you're saying that HiDPI mode in Lion is a guarantee that new Macs will have retina displays, and that if they wait til WWDC to release them, it will only be because of some sort of manufacturing delays, and not because it would make sense otherwise? Just want to clear some things up so we can make some progress in our healthy discussion.
