I think it would have been about a 3 way tie, although I'll give the edge to Sony, since that is what actually happened between Sony vs. Microsoft. Here are some factors to consider:
-As others have said, Nintendo does not get most of its new customer base that it would have gotten from Wii.
-I agree with Bofferbrauer2 that the Virtual Console was something of a selling point, and "Wii HD" would still have brought in some old school gamers like myself.
-Nintendo launches at a $300/$350 price tag means it is the cheapest HD console on the market. That gives it something of an advantage as well.
-Third party companies were gradually transitioning to making their games multiplatform. Microsoft was the main company championing this, but Nintendo would get some of the benefit. This means that the "Wii HD" would have had a better third party library than the Gamecube, but not as good as PS3 & XBox360. (Take the average of the Gamecube and PS3 library sizes and that is a decent estimate of the "Wii HD" library, and then add in Virtual Console games.)
In the end I think Nintendo steals a very large chunk of the XBox360 audience in NA, and it also steals a decent amount from Sony in Europe in Japan. The "Wii HD" sells to 3 groups: 1) Gamecube fans who stay loyal to Nintendo, 2) People who just want the cheapest HD console (a huge selling point for the XBox360 originally), 3) old school gamers who return for the Virtual Console. Put that all together and I think Nintendo sells about as much as XBox360 and PS3. Perhaps they all sell about 60-65m each, and again I give Sony the edge.
Also, given the lack of a $250 console that appeals to new gamers, I'd say DS sales go up about 10m, which would end up putting the DS above the PS2 in lifetime sales.
