Earlier today at the Web 2.0 Summit, Research In Motion’s co-CEO Jim Balsillie sat down to discuss the future of BlackBerry devices. During his interview he gave a few small details about the PlayBook that we previously did not know.

We were shown a video before Jim’s interview of the PlayBook versus an iPad in web fidelity. Jim Balsillie continued to reiterate that the PlayBook is 3 to 4 times faster than the iPad. Jim went on to discuss how the PlayBook will have features that will help make it innovative. One feature he mentioned was that the PlayBook should have a module cavity.

A module cavity will allow the PlayBook to be upgradeable. This could be useful in terms of taking the PlayBook from 3G to 4G/LTE. Therefore, letting you upgrade without having to purchase an entirely new device. The module cavity may even play into the PlayBook’s wireless connection, allowing you to change it between a slave or master unit.

Jim also mentioned that they would be ‘fools to not include NFC in the future’, which we mentioned seemed likely with Isis. He also noted that we should see more PlayBook demoing within the next 30 days. So far the PlayBook seems to be shaping up nicely. Are you excited for its release in Q1 2011?
