My suggestion is that first reserve, first serve is that it would spur reservations, and that these will have to be turned into sales in one day (hence the two day advance sale unlike the present day before launch). If not, then reservation would be cancelled and probably prevented from availing of future sale promos. But it's up to PinoyDVD to decide what way they think is best for all concerned.
As to number of dog tags, my guess is that it's a trade secret and best for PinoyDVD to keep it close to their chest.
And on my posting of November 12, maybe I got my dates mixed up, thanks for correcting me, or else, I would be waiting the whole early morning of the 12th for PinoyDVD to start accepting sales of the Ultimate edition.
