1. iPhone will be released (as known before) and Jobs will showcase a slew of new and exciting features. [Now known to be true*]
2. A new, widescreen, touch-screen 6G iPod using the new touch-screen gadgetry tech from the iPhone. [Now known as iPod touch*]
3. The release of a completely redesigned iMac, maybe including a black model and maybe featuring touch-screen/multi-touch technology? [Redesign happened, no touch abilities*]
4. Cool new Leopard features, including multi-touch support and a completely redesigned GUI named "Illuminous." This new GUI will encorporate the new interface elements from iTunes 7 and will look sort of like the Effects palette in iPhoto 6. I got this rumor from [http://www.applegazette.com/mac/rumor-aqua-to-be-replaced-with-illuminous/]. In my opinion, Apple will probably make some minor refinements and small style changes in regards to GUI with v10.5, like in the previous OS X releases. Aqua's much too famous and recognizable to completely replace; rather, if Apple wants a new look, they'll gradually nudge in the right direction. [Came sort of true, in the sense that Leopard has a universal GUI separate from Tiger*]
5. New releases of iLife '07 (maybe with iTunes HD - iTunes Store with HD content?) and iWork '07 (new spreadsheet program?). [Came true, called iWork '08 with Numbers*]
6. Cancellation of the Mac mini line (probably not announced with much fanfare). [Eh...wrong*]
7. Release of a "MacBook Mini," a new ultra-portable notebook (maybe a smaller MB Pro model so Apple doesn't have to create a third product line?). [Now known as MacBook Air*]
Those are my predictions, and, while obviously not all of them can occur THIS year, I believe that these products/releases support general direction in which Apple is steering itself. After WWDC I'll add another post to compare my ideas with the actual results. Thanks, Masoni
