Okay, this is quite simple.
Look at my post (btw, you should read the thread it is in, it is quite educational on the subject). http://www.vgchartz.com/forum/post.php?id=1390360
Do you believe that the Ps3 can manage to tie the 360 by end of 09? If you do, do you think it can by end of Q2 09 (remember to read my post, it gives some info on what you just said you believe).
If you believe it will tie the Ps3 by end of 09, do you believe that the Wii will have 50% market share before that?
I don't even believe the Ps3 will tie the 360 by the end of 09, but I think that the Wii will hit 50% market share before that (ala, end Q2 09)
