Video Game Chartz reports:
"When compiling weekly data for Japan, ioi uses a bevy of sources. By Sunday Night (East Coast USA time), both first day data and preliminary weekly data is available for analysis. Taking both into account, here is an early take on how some of the figures will look this week. These figures are not to be taken as gospel, just an early take on approximately where the market will be for the week.
This week saw a huge amount of software sales, and seems to mark the seasonal upturn in videogame sales as December approaches. However, the release of Dragon Quest IV for the Nintendo DS – at any time of year – would have caused an enormous increase in software sales all by itself. What makes this week huge is the fact that seven titles sold over 50,000 units this week. As expected, Dragon Quest IV was indeed the top selling title of the week, although it looks as though both the PS3 and PS2 versions of Winning Eleven 2008 debuted to strong sales as well".
