Yes,, I recently purchased the 65" S2 (great TV) but I have a friend that wants to buy it if I decide to sell it to get the ST30 but I have to decide sooner than later as the buyer might not wait much longer.
I still have my 55" LED Vizio as a back-up if needed.
One other idea Im considering,, keeping the S2 and getting a passive 3D LG or Vizio,,, while at CES I found I like passive 3D more than active.
But to be fair I did not check out Panasonic's "claimed" improvment with their active 3D,,, Im kicking myself in the ass for that one,,,,I really should have took the time to check out the 3D on the new Pannys.
One of the main reasons Im interested in the ST30 is I want a 3D panel in the house, I hate to buy a passive panel just for the 3D but thats what it might come down too.
There are some other considerations as well, but thats the short version.
