Apple is moving towards removing the dvd drive: The App Store for Mac means that Apple is moving away from the traditional software model where you would buy it in a store with a physical dvd towards digital downloads. That brings me to my next point. Apple is phasing out boxed software from its retail stores. Apple is experimenting with getting OS X Lion via the App Store. Currently, the only way to get OS X Lion is through the App Store. Apple is not afraid of removing the DVD drive. The MacBook Air has never had a DVD drive and they were one of the first companies to do so. AirDrop in Mac OS X Lion. Who needs to burn files to a disc when you can effortlessly share them over WiFi? Thunderbolt makes external storage and dvd drives faster than ever. Apple is clearly shifting away from the optical media. Improving SSD technology With the removal of the dvd drive, there is now more room for a larger battery and a supplemental SSD in addition to a normal hard drive. Mac OS X Lion has TRIM support. This command improves the durability of SSDs and reduces potential performance problems. SSDs are ready to go mainstream. Apple is increasingly using Intel technology (Sandy Bridge graphics, Thunderbolt, etc). Which brings me to my next point. Intel is working on SSD caching technology, which allows a SSD to act as a cache for a larger hard drive, similar to the Momentus XT. This tech is featured in the upcoming Z68 chipset for Sandy Bridge, and will likely be in the chipsets for the Sandy Bridge sequel, Ivy Bridge, to be used in the next MBPs. This means the new MBPs will feature a standard SSD for speed, much like the MBA, but also have a mechanical HDD for storage. New cloud storage features in Mac OS X Lion. Less reliance on hard drive space. Apple is clearly moving towards SSD mass adoption. Apple barely even acknowledged the most recent update. The next one will be big No fanfare, no announcement, merely updating the Apple Store This is not seen as a major update, because it is nothing compared to the next one. Liquidmetal, anyone? Apple's OS X Lion represents its commitment "Back to the Mac". A major hardware update to go along with its major software update follows this mantra. In conclusion, the combination of new developments in SSD technology, new features in OS X Lion, as well as Apple's shift away from physical dvds all point towards a major update when Ivy Bridge comes. Ultimately, only Apple knows what is really going to happen, but because of sheer amount of evidence and motive, I believe the next MBP update will be a major change from current models. P.S. A bit unrelated but still significant is the new Ivy Bridge GPU has DX11, full OpenCL support, and will be 30% faster. Get used to it folks, no more discrete GPUs for the 13" models.
