So, we've just been discussing the rumored, and long overdue, MacBook Air refresh with a trusted source. This person recently had a working model in their possession for a few minutes and managed to glean quite a bit of detail that would seemingly confirm Apple's plan to announce an 11-inch MacBook Air at the "Back to the Mac" event later today. Here's what we've been told to expect: Unfortunately, our source couldn't identify the graphics or the storage related to the rumored "SSD Card." So where does that leave us? Well, it looks like a smaller (and presumably, cheaper) MacBook Air originally rumored by AppleInsider is in the bag for a Steve Jobs announcement later today as is a refresh to the 13.3-inch model we broke last week (pictured nekkid above). So check back in a few hours and watch the reveal live, won't you?

Update: Reader Lucas F. submitted a mockup of the new power and eject keys which you can see after the break.
