I finally decided to stop reading and start going out and really looking at different products.
At the store I checked out the 2D to 3D on the Samsung for movies and for Soccer ( I watch Hockey but thought it would be comparable).
I was not impressed at all and ultimately bought the VT25. I think when you first see 3D there is the "wow" factor, but once that is over, its going to come down to content that is filmed with 3D in mind. Otherwise it really is just a gimmick.
Since I've gotten the set home, I am absolutely floored how good the blacks and color accuracy are. The 3D effect is so much better with darker lighting and without other TV's around to set off flicker.
I guess the question for the GT25 is whether Panasonic is using any different algorithm than the other manufacturers for 2d->3d.
