There really isn't - Wizkids has been selling blind boxes for years and they're fun. I don't buy them as much anymore because the price has gone up more than I think they are generally worth, but I've purchased my share in the past. In general, I have found them an affordable way to get my hands on miniatures for repainting, often cheaper than buying the unpainted version, even when I knew exactly what I was getting. As well, depending on rarity you can get some really great miniatures for cheap on the resale market (though, again, those prices have gone up a lot in the past few years).WizKids is a partner of WotC and have a license to create D&D miniatures - it is not a heck of a leap to envision WotC themselves participating in the same model elsewhere, and as for collecting miniatures, there is a distinct difference between knowing what miniature you are buying and purchasing a blind pack in which you are not sure what you will be getting.
And anyway, what's it to you? If I want to spend my money on miniatures, analogue or virtual, sight unseen or not, why is that anyone else's business? If WotC want to enter that market, then people with either buy their stuff or they won't. Same with the VTT - it'll either be good enough to get folks to pay for it, or it won't. I'm not seeing the issue - D&D is basically free to play, with the basic rules, or really cheap with the three core books, and anything after that is gravy. I spend a fortune on miniatures and terrain because that's my jam, but lots and lots of tables have as good a time with pencils, paper, and their imagination.
