Destiny has around 2.6Million pre-orders. Gaining about 100k weekly. The 100k will most likely jump to around 500k for the last week of pre-ordering. So figure around 4million sales day 1. This game will be on the list of best selling games day one. Your cancelled pre-order means nothing. You will account for a 0.000025% drop in sales. No one cares.
I have been playing games as long as I can remember. Yet Destiny is the only game I have ever Pre-ordered. That's how Amazing it is. And I know it is because I played the Beta. It broke my heart a little when they shut it down.
