It seems that the game companies are releasing their big titles for a lot of money, but the they take a risk cause that price goes down a lot. For example I picked up Shadow of Rome for about 7,000 yen. The other day, just a week or two after its release the game store I bought it from is selling it for 4,900 yen.
I went to akihabara yesterday and Spikeout Online was 6,800 yen, and kof 2k2 was 4,300 yen. (I bought Kof 2k2 and it rocks)
Im excited for Kof Neowave. Its got some new pointless features like the heat button. I just hope it gets an xbox live release!
