Like you Soulcatcher, I thought the pros preferred the forged blade irons. Some quick googling shows that while many pros still use blades, quite a few pros are using what I would call game improvement type irons with various weight distributions. Check out this list
Irons used by PGA Tour Professionals
Though somewhat dated, 2007, it does show the use of Ping S58's, I5's & I3's, Callaway X-tour, and TM r7's. None are the classic blade irons.
All this makes me hopeful we will see a Master Rapture set. Probably with steel shafts.
What is missing in the WGT Pro Shop is a true blade iron. Maybe that is being saved for when/if an Elite tier is introduced.
