Hmmm, should people really be focused on the price? I don't know, even the MGS GZ price tag doesn't seem that much bad. I mean, both Naughty Dog and Kojima productions will deliver an extremely high quality piece of entertainment,specially for fans of the series. The best thing people could do in this situation is fight with your wallet. Complaining about the price or anything like that doesn't make that much a difference.
When L4D2 was bein boycotted by fans of valve, in the launch day, a lot of people that said they wouldn't buy the game, in the end they bit the bullet and played on launch day. Gabe Newell even stated that this meant that even though people were mad at first, they saw the value of the game in the end.
