In a recent Gamasutra interview, Colin Sebastian of Lazard Capital Markets suggests that year-over-year software sales for January may be up as much as 30%. Driving this push are Lost Planet and Wario Ware (Wii). Other Xbox 360 titles expected to aid in overall sales growth include Call of Duty 3, Rainbow Six Vegas, and (duh) Gears of War. Should the prediction hold true, it would mean a strong start for 2007. With lots of exclusives and system selling titles shipping in the next few months, here's hoping the 360 maintains its momentum through the typically dry spring season.Official NPD numbers are expected February 15th.
