Final Fantasy is an iconic franchise and one that should always rake in plenty of profit for Square-Enix. Hence, their lofty sales prediction for FFXIII isn't surprising in the least.
According to Andriasang citing a recent Reuters interview with S-E CEO Yoichi Wada, the company expects the newest FF iteration to ship more units worldwide than its predecessor, which means FFXIII would have to top 6 million units. Wada also mentioned that the price drops for the PS3 and 360 should help push sales even higher and furthermore, he wants to remind everyone that Square-Enix is no longer a one-trick pony. He emphasizes the new stuff; saying they've got "two or three titles" scheduled to be released towards the end of next year that might wow the crowds. Furthermore, they want to have "around 8 IPs that could provide a continual influx of 2 million unit sales for the company." What are these 8 games? Well, one of them is undoubtedly the freshly revealed Nier but beyond that, we'll just have to wait on pins and needles for more IP announcements. Also, bear in mind that Square-Enix now includes Eidos in their stable, so Wada could very easily be referring to several titles from that side of the corporation, too.
Square-Enix has yet to really make their mark this generation; everyone is waiting for Final Fantasy XIII to keep us fat and happy for months. But don't discount the other stuff they're working on…new IPs are always interesting.
