Yes, transmitting a signal that is incompatible with every existing tuner that is now out there is real likely to be a winning strategy. Really, I do not understand the COFDM obsession that some people seem to have -- I'd say that ship has sailed many years ago.
Aside from that, if the FCC were to opt to allow the switch to a transmission standard that is totally incompatible with every tuner that is currently out in the field, it would be an opportunity for even greater mischief. Simply put: if the FCC is going to obsolete every existing tuner, why not use that as an opportunity to shrink the width of each channel. Give each broadcaster a 2 MHz channel (sufficient for 720P using the latest compression codecs, or for SD multicasting), and suddenly it would become very, very easy to reclaim vast chunks of spectrum by fitting all existing stations into the VHF-hi band and the bottom ten channels of the UHF band. Note that I'm neither advocating this or saying it will happen -- but just pointing out that if you're willing to obsolete existing tuners, it does open up "opportunities" that few of us here would want to s see pursued.
Be careful what you wish for...
