My guess is that the 3D Pannys are just more susceptible to it. I'll keep a closer eye on the ST60 to see if the "improvement" is for real.
It'd be great to hear back from you after you've spent some time with the ST60 if possible. I doubt any actual review site is going to be doing IR testing (that CNet test last year was an accident), and I haven't heard anyone else who's familiar with the 2012 IR saying they've purchased a 2013 model yet. I think there are plenty of people on here who'd appreciate hearing about your experience with it.

Serious long-duration IR can take a good bit longer than that to resolve in my experience. I had a particularly difficult HUD element from Borderlands 2 that took a full 36 hours of fairly bright content to go away. Has it gotten any less distinct at all?
IMO the 2012 Panasonics represent a really odd middle step in Panasonic's plasma development; they're far superior to the 2011 plasmas as far as overall picture quality, at least from what I've observed, but it seems they compromised some basic issues like IR performance and screen uniformity in the process. From everything I've read so far it looks like it's possible that the 2013 models are essentially the "2nd gen" versions of the XX50 technology. Of course this may be consistent with technology development in general (large step forward with potential issues introduced, incremental update that fixes some of those issues, repeat). I might feel bad about my purchase of a 2012 model if I hadn't gotten it for such a low price. As it is, I won't feel particularly bad picking up a VT or ZT later this year (assuming the IR really has been sorted out).
