Nothing is infinite. Tell me how many preorders exist and I'll start caring.
Considering it's a limited edition, I'm gonna go with a limited amount. Considering it's the same people who made the extremely limited MGS HD LE, I'm gonna go with extremely limited.
All preorders that are cancelled are put back up around release so it's not a problem for those that want to place a order but are not sure if they want to keep.
So the people that do know they want it have to sit by the computer for days hitting refresh because some asshole pre-ordered it and then canceled it at the last minute? Look at what happened with the Virtue's Last Reward pre-order bonus.
Granted, I got completely lucky in getting my MGS HD LE because some people canceled their pre-orders and I was on the site right when someone posted about it.
I don't know, maybe I'm just weird in that I buy things that I want and I don't buy things that I don't want and I'm able to make that distinction about everything. I don't just place an order for everything that I may be marginally interested in at some point in the future.
