What do you guys think Steve will announce at MacWorld? I think he'll announce some kind of Mac tablet for sure and a new Apple TV. I wouldn't doubt getting iTunes movie rentals, and if we get really lucky, HD movie downloads through iTunes (c'mon Apple, SD iTunes movies on a TV or a HDTV suck). I highly doubt this will happen, but I'd really like to see a MacBook Extreme with SLI and dual HDs. I think we have a good chance of a MacBook Pro and MacBook case redesign, it's been five years, and the MBP has had the same design since the last gen of the PowerBook. And finally, Steve Jobs will (hopefully) announce new features for the iPhone with a 2.0 firmware update including the full SDK we've heard about and tons of new features. I doubt we'll get a 3G iPhone until atleast August, but Apple wants to sell as many iPhones as possible so coming out with a 3G iPhone by summer wouldn't be a bad idea, combined with a new firmware update with features we've been waiting for since launch, Apple has the potential to make announcements that'll sell a lot more iPhones, check out this old thread:
And finally, one of my biggest doubts, but something that everyone would benefit from, Apple taking gaming seriously! Giving OS X better native support for games, giving options for high-end video cards in every Mac model, and slightly redesigning every Mac to run cooler and support for video cards that use more heat than your average card.
