They are pissed because DR or Namco has no sense of business to sell so many copies to one person.
It's not uncommon to limit quantities per person. The place I buy comic books from limits purchases to two books per customer and sometimes even one for certain books. It gets rid of the resellers.
Another example is the new Zelda art book. I think almost every retailer had a limit. Specially on the limited edition which there was only 4,000. You can't just buy 1,000 copies because you have the money and then flip them.
Buying 200 copies is wholesale which shouldn't be for something that was retailer exculsive.
It is weird that Namco shipped so many copies to PlayCanada who then proceeded to list above MSRP. But when they had the Ninostarter campaign, in which they set certain goals that when enough preorders were submitted, new content would be added to the LE, it was made absolutely clear that they were prepared to make as many units as consumers asked for.
PlayCanada, and any ebay resellers who bought multiple copies, were actually doing consumers a favor by not only helping to reach Ninostarter bonuses, but also increasing supply overall. People who dislike those opportunistic sellers in this particular case are hating just out of jealousy of their financial success, nothing more.
