I can confirm that ALL orders for the TR 40 are in the process of being cancelled. The unit no longer qualifies for the converter box coupon, and as Provantage has already processed the existing orders by redeeming the $40 value from the card, they have no choice but to simply give customers credit for the value as it cannot be reloaded on the card.
I just got off the phone with Provantage customer service regarding this. They have thousands of pre-orders for this box, so it's taking them some time to process all of the cancellations, but no orders for this unit will actually be processed. Instead, they are recommending the TV/Pal replacement unit for new customers and are supposed to transfer existing orders to that unit as well (as far as I know, it's the same thing as the TR 40 - just a name change).
In fact, because of the DTV processing site maintenance underway today, Provantage is not accepting ANY converter box orders today. They want people to call tomorrow. I suspect this is going to be an issue with a lot of retailers. There is a maintenance notice on the DTV merchant website about a planned outage although I didn't pay attention to the exact details.
Existing orderers may want to doublecheck they are on course to get the replacement box automatically.
