And you want my prediction? Even if you don't, here it is.
Absolutely nothing is going to change. Domain investors are unusually quick to adapt to a changing market, so WHC will make a bit more on their Premium Auctions, but they'll lose some of their old $20-$50 market to other registrars. So it'll be a wash unless a ton of premiums start dropping on a weekly basis, and I don't see that happening anytime soon.
The .CA investor/wholesale market is small and .CA domains are not exactly flying off the retail shelves

. It's a tiny market with a finite weekly budget and I don't see how moving to a new auction format is going to significantly change revenues over the long term.
The only thing that might do it is a huge upturn in retail .CA sales to companies and other end users, but that kind of shift is not anticipated and is also not within our control.
If you know anything about business, then you realize that no amount of hype or capital infusion in the wholesale market will ever create long-term .CA growth unless is it matched by a commensurate jump in the the volume and pricing of .CA retail sales.
You can only buy so many domains before you figure out you also need to sell them at some point in the future, so there needs to be adequate money at both ends of the equation to create sustainable .CA growth.
So TBR registrars can hire dancing girls, runs ads, give out free hamburgers, and switch auction formats like I do underwear (daily), but that by itself is not going to change anything over the longer term.
