Who knows at this point :/
Exactly. I think the panic here is a little high at the moment when we don't really know how this wave will do in stores. If you told me that Mega Man and Sonic would be commons a couple months ago, I would have laughed in your face. I think Pac-Man, Wario, and Charizard will be commons. Robin and Lucina is the questionable one right now.
If people missed out on the recent preorders, all hope is not lost. More preorders will open I highly expect, just like all other waves. These retailers have to play it safe right now with the preorders to avoid the debacle of earlier waves. So, TRU and Best Buy and Target are not being jerks, they are playing it smart and only allocating so many that they highly expect to fulfill. Better to only have so many available for preorder, then have more waves of cancellations right? Keep checking this thread to be on the look out for more preorders. They will come!
And let's get off Nintendo's case
Producing amiibo is not a cheap process. On IGN's NVC podcast, they said it takes a good month of production to produce amiibo to satisfy retailers. Nintendo does not have unlimited funds to produce millions of amiibo to make everyone happy. This is not their main business. They are still a video game company. Companies have budgets, and their main budget is not amiibo. Grant it, we all wish they would make more and more, but that is not the case.
