Apple are looking to close off the year (in terms of keynotes anyway), with Steve Jobs talking about the Mac. The 4 keynotes previously in the year, focused on the iPad, iPhone and more recently the iPod line up.

If pictures paint a thousand words, the invitation clearly shows a lion, so one would assume that this event will be the unvaling of Mac OS 10.7 Lion.

As I like guessing a bit too much, here are my predictions for what we will see in Mac OS 10.7.

What I think will be in it:

• FaceTime
• AirPlay
• A replacement for Finder

What might be in it:

• UIKit (or some additions to AppKit to make it a UIView based system like the iPhone i.e. NSCell is a subclass of NSView !!!
• A Mac AppStore (hopefully it won’t be the only way to get software on there)
• Support for 64 Bit, Multicore systems only.

What needs to happen but won’t:

• Decoupling of iTunes into separate applications (Store, Library, Device Manager etc)

Other than Mac OS X, there is more than likely going to be a Mac hardware announcement along side iLife/iWork 2011. The MacBook Air seems to be the safe bet, but I also expect the entire MBP line to get a speed bump … Can I wish for USB 3.0 ?

One more thing … Maybe we get to find out what the “revolutionary feature” is.
