I don't know why you use the Dreamcast to proof how horrible the PS4 is doing, the Dreamcast had a slow launch but consistently sold well in the first months, if we exclude the launch period then it easily beat the Wii U as well for example.
Anyway I'm still fairly certain that the PS4 will end up the leading home console this gen in Japan, how many consoles that will mean in the end we'll have to see.
