Ok.. a few updates.
Sharp failed to call me back twice in a row on their commitments for case updates on the 3d crosstalk./ghosting issues. That plus the growing frustration with the clouding in my set made me return the tv to Costco. They were more than reasonable in refuding the purchase + warranty. I pulled the trigger on a 60" Elite the same day and have been happy since. The ghosting/crosstalk is noticably better on the Elite. No clouding, incredible contrast, and a much improved/smoother 3d plackback. Some areas that would pause for me before on the 8470 are butter smooth on the elite. My glasses all worked on the elite fine, so no loss in investment there.
I ordered a pair of Dimension Optics 3d glasses which the local Sharp rep said was the only OEM model they recommend for 2011/2012 models. I didn't notice any difference in the picture quality between that and the Sharp model 3d glasses. I would say it comes down to comfort as the Dimensional Optics glasses have a different shape and feel on your face. If you do not feel the Sharp glasses are comfortable these might be worth a try. The one downside to these glasses is that they do not have a 2d/3d switch on them. They do come with a decent hard case for protection.
As for my existing case with Sharp. They did call me back late on Friday when I was out of town (they have my cell as well but never use it). The case update was that the technician assigned to my case reproduced my problem using Tangled 3D bluray. He admitted they have an issue and they are going to try and address it with a firmware update for the tv. Good news for those of you who were waiting for an update. I won't close out my case as I hope they can improve the performance for everyone else here.
For now, I'll enjoy my elite. The only issue I have on that tv is an audio sync issue over hdmi to one of my components that I did not see on the 8470.
The kids 3d glasses have not arrived yet. There was a miscommunication between the vendor and I which hopefully is now resolved. The vendor had not tested the glasses with the 8470 or elite and was unsure if I wanted them shipped still. On his approved list was a sharp 835 and 925 series which should be compatible with both models from my research. I will update this thread after the glasses arrive and even test them on an 8470 or 845 to verify they work.
