With Dragon Quest IX out of the way, Final Fantasy XIII is Square Enix's biggest game in the pipeline. The company apparently has high hopes for the title.
Responding to a Reuters interview on the 28th, CEO Yoichi Wada revealed that Square Enix hopes to see Final Fantasy XIII ship more units worldwide than its predecessor, PlayStation 2's Final Fantasy XII. This would mean shipments of over six million units.
He expressed hope that the recent PS3 and Xbox 360 price drops will help push the game's sales.
Wada also provided an update on Dragon Quest IX's sales state. Domestic shipments for the game topped the four million mark last week. Wada said that while he believes the game will top the five million mark this fiscal year, reaching the goal will cause pressure to Square Enix management.
There may be more to Square Enix than just Dragon Quest, Final Fantasy and Kingdom Hearts. Wada said that the company has two to three titles that it hopes to be banner games to follow Dragon Quest and Final Fantasy. "These could be released at the end of next year or the year after that."
He also told Reuters that Square Enix aims to have around eight IPs that could provide a continual influx of 2 million unit sales for the company. Development time is two years, so with eight games, they'd be able to have at least one release every quarter.
One thing to note in all this talk of banner titles and new IPs. Yoichi Wada was addressing Reuters as CEO of Square Enix Holdings, which also covers Eidos. He could very well be referring to titles developed outside of Japan rather than the next Tetsuya Nomura hit.
