I'm looking to upgrade primarily the size and to get a 1080p display. As of now I do NOT have room for a 65 so that's out. The 60 is really pushing it but could probably be done.
I am leaning towards the 55VT50 because it gives me plenty of picture controls to dial the set in and I think coming from the Pioneer, I'll want to tweak the set to squeeze the most out of it. Right now my viewing distance is about 9 feet away. However, it is becoming increasingly likely that we will build a house early next year and the VT will wind up in a theater room where the seating will likely be closer to the set. Likely 7 to 8 feet, maybe a bit closer for the first row.
The wife ultimately wants something smaller downstairs at the new house, probably a 40 or 46.
