Absolutely not.

I could believe total sales outselling the PS3 in a single territory like others or NA perhaps (though still an insanely long shot) but not total.

 -edit-

oh!  Christmas 2009-- missed that part.  Not a chance in Hell even if we're just asking about territories. 

Not a chance, wii sports maybe but not wii fit.

Why? The hardware, I don't think that out of the 60M (est.) or so wiis sold by christmas 2009 there would be enough people who would invest in a wii board. But hey that's just me.

hmmm... glad to see not all people are on the verge of insanity..

Wii play is just barely behind the PS3 in terms of world wide sales. Wii play is an easy attach for the controller, but it is not a system seller. I expect Wii Fit sales to exceed that of Wii play. (Not really to hard core gamers, but that is not it's focus audience, but there is some overlap).

Wii fit on the other hand is a system seller. In NA, people not otherwise interested in video games will get a wii just for wii fit.

If you only look at NA, then Wii Play is already > PS3. 

Worldwide, by the end of 09, I don't think it has a shot. Wii fit sales worlwide outselling PS3's in the US/Europe, probably quite likely.

That's just crazy talk!!!

Wii Fit will only outsell the PS3 in Japan.

people still comment on this?
wtf? =))
PS3 will reach 45-50 mln. by that time. =)

These games will sell, 1 mln. GT5P in Europe prove that. =)
Looks like, all you need is to wait for MGS4 release and sales. :)

its close to passing the PS3 sales in japan, but i doubt it will pass NA,others, and japan al together

but it might be close
