I saw an "upgrade" with a retina display and a 256 GB flash drive and 8 MB memory....but I'm not sure on prices...that it's worth the upgrade cost. Here's the model #.
The one you linked: MD103LL/A
The "upgraded" one: ME293LL/A
The "upgrade" has a lower graphics processor (but still sufficient)....if you're not playing demanding games.
