Online Ad Evidence of Imminent iMac, Mac Mini and MacBook Updates?

Feeding into recent rumors of imminent iMac, MacBook and Mac Mini updates, some new online ads have been spotted at that potentially point to new versions of these products. While Apple's Google text ads always refer to their products as "new", these specific ads do highlight features that have not been the focus of previous revisions. The translations provided by AppleInsider describe the possible changes:

MacBook: Thinner, lighter and faster! Free delivery. Order today.
iMac: Ultra Thin 20 & 24 inch models. From only €1099. Apple Store
Mac mini: Faster and more affordable than ever. From only €499. Order immediately.

Of note, the current price of the Mac mini in the Netherlands online store is €599.

These imminent updates were first reported back in September with the iMac specifically described as "thinner, organic design, likely with smoothed or rounded edges".
