^Here we go, an online fee (and dozens of other things while WW & VC are offering games only, even DLC offerings are limited on Wii). Just like I've said you may twist it that way and you'll be absoulutely right - revenue is quite bigger - and publishers may find it more lucrative.
I lost this one, or rather I was driven away by non-essential info, but let's get to your initial point "Wii users perhaps don't typically buy much software...", which is no way proffed by bigger revenue streams in downloadable sector since serivces are quite different at monetizing content and offer a hell lot of other things not even gaming related, while retail games sales are giving us entirely different picture and it was quite possible assumption that tie-ratio of downloadable games on Wii compare favorably with other platforms as well.
