Since info on these SXRD models is so spread out in this thread, here's a recap based on everyone's comments so far. Based on my sources, this information should be correct, but you can never be 100% sure until you open the box.

Dimensions & weight
KDS-R50XBR1: 57-1/4"W x 34"H x 18-7/8"D; 94.8 lbs.
KDS-R60XBR1: 66"W x 39-3/4"H x 20-1/4"D; 112.5 lbs.
i.LINK ports appear to be HD-compatible like those on the Qualia 006. In the "i.LINK Setup" description, the example shows a JVC D-VHS deck as the source.
As you may have gathered from some comments about the A10 Grand Wegas, there are two parts to Cinema Black Pro. First, there's a global iris adjustment with, I think 4 positions, that's designed to compensate for various lighting conditions in your room. The separate Advanced Iris "dynamic iris" option is one of several video adjustments that are only available in the "Pro" picture mode.
Hope this is useful. To those folks who had to scratch the SXRDs off their lists due to the side speakers: my sympathies. I was surprised, too. To everyone else who's still considering the 50" or 60": I'm still convinced the picture quality will be worth waiting for.
