Saw a 13" rMBP in store today and the glassy screen wasn't as reflective as the non-retina glassy ones. So I'm getting slowly used to the notion I could live with a retina type display. Loved the form factor of the 13", but currently only in 8GB RAM max. Questions... 1. Can one upgrade the RAM to say 16GB themselves, or are they soldered on? 2. What are the chances the next revision will see a bump of the RAM up to 16GB, and I guess the 15" to 32GB as a CTO? 3. And a bump to a quad core processor?
