I think you are probably right. Large companies will take these for vanity/defense of brand, but I won't hold my breath for mainstream adoption. What was the uptake like on info, name, pro, biz? Not much. If a large corp wants to use these to brand an area of "mindspace" like ".book" or w/e, they could have already done so through traditional branding avenues. - this will just be a 25k/yr adjunct to existing projects/products, but I doubt it will be anything of itself.
