Steve,
I am sure you are correct that some tanks will be taken down and some will live on. As long as people aren't throwing out their livestock and just putting it all back in a larger display I guess that is okay. I think the nicer nanos with a better shot at winning will be the ones that are intended to last and will therefor probably have more effort put into them.
And if you want a larger tank contest why not organize that yourself? I am now probably going to set up a 50 or 65 gallon tank as well so maybe I'll be into that too
