Speaking with Japan's Nikkei BP website, Konami president Fumiaki Tanaka revealed that Kojima is working on the concept for a new game outside of the Metal Gear universe. Pressed further on this mystery title, or possibly titles, Tanaka said that he couldn't reveal anything at this point and that a formal announcement won't be coming this year. Instead, we can probably look forward to hearing something after Kojima has written the new title's scenario, which won't happen until after MGS4 has been released and Metal Gear Online has been given a major push.
In other Metal Gear Solid 4 news, Tanaka revealed to the site that Konami expects sales to be similar to past titles. While the sales focus is on the European and North American markets, the company is aiming for sales of one million in Japan alone. Nikkei pointed out to Tanaka that the PS3 hardware has yet to hit the two million mark in Japan, to which Tanaka noted that many users are waiting for MGS4 to buy a PS3. He also feels that because a number of major PS3 titles from other companies will be released before MGS4, the system's userbase total will rise.
