Afilias took over .mobi, and that did not breathe new life in the TLD.
Perhaps their plan is just to buy extensions in order to kill them.
Even .tel got more registrations than .pro, so you can appreciate how popular .pro really is.
.tel and .mobi as many said were released like 10 years later than supposed to. Because the technology advances every day and is a very important variable to these extensions they are less used day by day, variable which does not apply to .pro
There are countless online websites that use PRO in their name but not in the extension though, because of PRO's meaning and that's the big advantage.
Again, .pro is in the top 3 used gTLDs (from the bottom) but the real question if this will change over the next years. There are many that say it won't and die just like .tel .mobi .asia etc but there are others + the recent facts that disagree. And by recent facts I mean :
- Afilias purchased the registry(the move will take place this summer as webdomain said) and they intend to bring this extension at it's true potential as the reported sales are begining to grow in value and number.
- At the auction organized recently by GoDaddy the highest sales were : Go.pro at 40,000$ ; Xxx.pro at 18,900$ ; Job.pro at 5,450$.
- Recent other sales(2012) : Tech.pro at 25,500$ ; Serrurier.pro at 7,620$ (locksmith in French) ; Business.pro 4,600$(re-seller bargain price) ; Telefon.pro at 2,225$ or Smile.pro at 2,200$ and other lower.
- There will be a bigger .PRO auction announced by Afilias later this year
-The restrictions for registering a .pro had been a big problem in the last years but now almost anyone can reg one.
-The reg fee dropped a lot.
Right now Table.pro is auctioned in sedo and Reboot.pro(website) on flippa with 5 figure offers.
