The Wii should do at least 20 mio units this year. Assuming it´ll sell at a weekly pace of 300k, the Wii would stand at 10,8 mio. units before Q4/10. The forths quarter is good for another 10 mio units, so we end up at 20mio+ units and so far, the Wii has performed better than 300k. So my guess is that the Wii will be close to 90mio units by the end of the year. If this happens, everything is possible.
