I purchased a 710 pioneer elite with a full cash payment, but have not taken posession. A few days ago, after learning what I could about the *new* *possible* *proposed* standard/protocal/b**sh**!, I contacted my vendor and demanded a letter either from them or, preferably, from Pioneer guaranteeing that my purchase would not be diminished (as it applies to HDTV) as a result of future technology. I requested this simply because I purchased this expensive unit to view HDTV! My argument was simply this: If Pioneer or your firm is unwilling to accept the contingency, how can you expect me to, when you are the professionals and I am only a consumer relying on your information and advice. Now, I am getting a full refund and am faced with the inevitable delema: Do I buy a cheap set, to "throw-away" if and when this protocal becomes reality? Or, did I over-react in my anger and walked away from a decently priced RPTV ($5700)? Comments are welcomed and MUCH appreciated..
