Unlike the now-defunct E3, Tokyo Game Show has always been an event for the masses. The public could wait on enormous lines to get their hands on upcoming video games (something I'd love to have here in the States!). The general success of an upcoming product can usually be seen by the approximate wait for the product.
Enter Monster Hunter Portable 2nd, the sequel to Japan's top-selling PSP game so far. The Japanese absolutely love this game, and according to Gamespot, were willing to wait for two hours to get their hands on it. Wow. (And they say the PSP is dead in Japan. Wrong!) Although the sequel will not feature any online gameplay, it does appear that the beautiful graphics will be enough to make the game an instant bestseller in Japan.
