Although digital sales are hard to quantify-  I don t think any objective person would doubt that XBox 360 and PS3 sold/sell multiples higher % s digitally than the Wii 

XBox 360 already surpassed the WiI in total physical sales and the PS3 probably has if digital was included  both on lower total install base

Correction: There is the fact that the Wii didn't move software...........relative to its instal base. And this only concerns 3rd party games. Nobody will tell you 1st party software was bad.

HUUUUUUGE difference.

It sold insane amount of 1st party software, it did not sell nearly as much 3rd party software and most traditional multiplat releases did not do very well at all, it also did not show impressive software numbers for a market leader or relative to installed base, especially when compared to the 360 (which is suspiciously absent in a few points in the OP).

The Wii sold a lot of software. It did not do very well with tradtional 3rd party games, it has a significantly poorer tie ratio than both competitors despite having several 10 million selling titles and even a few 20 million selling.

It did not "fail at selling software" but it largely succeeded in selling 1st party and more casual oriented titles, 14 of its top 20 titles are Nintendo published and/or developed and make up about 1/3 of the total software sales on the platform, all of which is totally fine, but let's not pretend that it comes close to 360 or PS3 in 3rd party fare.

The last two posts pretty much sum things up perfectly. There were fantastic Wii 1st party games, and I wouldn't have missed them, but yeah .. it was mostly a wasteland of garbage as far as 3rd parties, and much of it sold terribly (and that's a complex issue overall, but some/much of the blame can be laid at the feet of the third parties themselves, who were jumping over each other to release low budget waggleware or awful spinoffs). That's not the final word, but good enough for generalization.

Read and agreed. Irritating at best because it's basically true. There were a medicore number of legit ports of tentpole releases (not spinoffs, but things like NFS and COD mainline games), but they fell off fairly quick, and sold worse as the years went on (partially buried under a wall of garbage, and people learned to buy what they knew 100% was good on Wii : Nintendo 1st party flagships).

Wii not only sold great quantities of software, but was also capable of generate great profits.

Sorry but i think you are way to harsh here. Don't forget that Wii was just an overclocked Gamecube and pretty much an 6th gen console in terms of power. That's why in the beginning quality was higher because these games were also released on ps2/xbox. Once the industry moved on to ps3/360 they were pretty much forced to completely redesign any game to port it to Wii. By providing an uncapable system it's Nintendo themselves that alienated any serious third party support that was left after Gamecube.

it could also have been audience.  By 2008, it was pretty evident who the audience for the Wii was (children...mostly bought by parents, elderly,females and a very small "hardcore" base).  3rd parties and Nintendo themselves acted accordingly.

The wall of shame list numerous exclusives.  Whats the problem?

Yes because that's any game develpment teams dream, working on outdataed hardware with limited capabilities..... And most if Wii buyers were casuals, not the kind of people that buy many expensive AAA games. Wii simply wasn't worth the effort compared to the PS360 and it's third party game market potential.
