A couple things to keep in mind:
First, this isn't a thread about all problems related to Samsung PDPs. This is related to the AV filter or lamination on the screen itself. I can't help you with problems unrelated to this other than to tell you to call Samsung and insist it gets fixed. It took a lot of persistance to get this problem fixed and it may take persistance on your side.
Second, if you have peeling you should get it fixed. The warranty is limited in duration. There is a working solution, I got it, and can testify first hand to its effectiveness.
Third, there is simply no way to know if the peeling will get worse with age. I know a couple of you have decided to wait it out since most of the time the peeling is barely noticeable and doesn't intrude on the picture. But there is simply no way to know if it will get worse after your warranty is up.
Lastly, you should always return a set if it is broken or otherwise defective on delivery. If a company allows you to return it...do so. If you accept a delivery, knowing it is defective, you may not get warranty coverage. Triple check your screens upon delivery. Do not accept delivery until you are allowed to look it over thoroughly. If you have to tip the driver, so be it.
