We can only hope that the mini is not replaced by the rumoured cheaper iMac at WWDC. I don't think this can completely discounted, unfortunately. But then the reports of the mini's demise has often been over exaggerated. Long May that continue.
Instead, let's look at the glass half full. I believe we'll see a more 'mini' mini around Sept this year.
Priced more aggressively, (starting at US$499), it'll have the now common blade SSD, soldered RAM, dual TB2, decent (integrated) graphics, quad CPU and being fanless, it'll be super quiet. No FW, no 2.5" HDDs.
The way they see it, anyone who's using a mini as a htpc already has external(s) for the mass of media files. And for everyone else, small and sexy is better. If you need more, buy a more expensive iMac, or massively expensive MP. Just stop asking for the xMac. It ain't ever coming more that it did in 2011 with the 6300m.
