Probably the Wii will be down YoY for a month or so mainly because of shortages in US...then there are MH3, SMG2 and Metroid Other M, which will sell some more systems, and hopefully the shortages will end in April-May, so this year will most likely be better than 2009 (both sales and quality wise).
DS is reaching great numbers, 150+m LTD is pretty sure (hell, it may reach 150m even before 2010 ends!).
