Next Macbook Pro could be even lighter

Company's updated product could improve in one area. Maybe. It could also improve it in another area and not the other one. Possibly.

I'd rather use a fat and heavy notebook, but with replaceable RAM and battery.

Being able to get a 16GB MBA would tempt me about as much as a Retina MBA.

A slightly-lighter rMBP 13 or 15 would probably meet my needs, and would be Retina and 16GB. My MBA 13 2011 only has 4/256 which is kind of limiting. It's not quite worth upgrading just to go to 8/512/non-Retina.

I'll be disappointed if they upgrade the 13-inch MacBook Pro with Retina display and not the 15-inch.

if they keep removing hardware, like dvd drive last year, of course it's going to get lighter... and also less and less "pro."

I call BS!
