I can see Warhawk selling decent but the $40 PSN download price is too high. It would have done a lot better at $30 or less and that will drag the game down a bit.
As for tracking of the sales, I don't think Sony are all that bothered about it. If the game is doing excellent or poor Sony will report it one way or the other and in the end that is what counts. Sony will be monitoring the sales, especially since the development team exceeded budget, which means the game needs to sell more to recover costs.
