Combining those first two things together yields a third--1080p recording and playback. It seems that people like to use the iPad both as a means of consuming video content, and as a means of capturing video of important events. It would be nice to be able to record, and play that video in full HD.
4. 4G / LTE
3G is so 2010. There is speculation that the new iPad will include 4G / LTE wireless connectivity. While 4G networks are not as widely available yet as their 3G predecessors, it would be silly to continue developing devices that embrace yesterday's technology rather than embracing the future.
4G data speeds are significantly faster than 3G, which is important for a mobile device designed to consume data. Recent surveys have found peak download speeds of nearly 40Mbps for 4G, and sustained bandwidth that averages five times faster than 3G. The down side, though, is that 4G eats battery power faster, so Apple would need to boost battery capacity to maintain the same endurance, and that would add weight to the tablet.
5. Bring on Siri
Siri is uniquely useful on a smartphone, but since the launch of the iPhone 4S it has been assumed that the next-generation iPad would also include the virtual personal assistant. It would be just as nice to be able to ask Siri to schedule an appointment, check the weather, or get the latest stock market figures on an iPad as it is on an iPhone.
In fact, it would be nice if Apple would expand the capabilities of Siri to integrate with more of iOS. Apple could make Siri more functional by allowing you to tell Siri to take a picture.
Even better, Apple should let you designate the default app for iOS to use for certain functions. For example, I should be able to designat Garmin StreetPilot as my GPS / mapping app, or WeatherBug as my weather app of choice, and when I ask Siri for directions or weather information it should use my chosen apps instead of the iOS defaults.
6. Economy iPads
While it won't impact the iPad 3 itself, Apple can shake up the tablet market by offering some different options at bargain prices.
When the iPad 2 came out, Apple reduced the price of the original iPad to clearance out inventory. I expect Apple will do something similar for the iPad 2 when the iPad 3 comes out, but Apple could stir things up even more by not just clearancing the iPad 2, but continuing to offer it at the discounted price as an economy model of the tablet, just as it is continuing to produce the iPhone 4 as an econo-smartphone option alongside the iPhone 4S.
