I think we are seeing a gradual shift away from tactical. Case in point, Benchmade. Several years ago they were leading the production tactical movement with the AFCKs and the Emerson CQC7s. Well, they still produce some great full-on tacticals, but they have diverged from that path with models such as the 550, 450, 330, 940,770, and the Outbounder fixed blade.
William Henry's stuff is still gaining momentum, and will accelerate rapidly once the ICONs hit the market. The ICON is a different type of gentleman's knife with a big size, light weight, and the MattLock, their own lock design.
Tactical will always be on the knife market and will be a favorite among knife users, but It's not going to be as prominent as it had been several years ago.
As Dennis pointed out, we are seeing an increasing number of low-cost knives. Both USA made and overseas. Back when I got into knives, if you wanted an inexpensive knife, you would have to settle for one whose design was kind of "blah". Nowadays, we've got the KErshaw lackout, Whirlwind, Scallion, Chive, and Vapor along with the CRKT stuff (pick any of the collaborations - Carson, Viele, Crawford, et. al.), and Camillus' EDC. These knives offer performance and value along with a key element - style.
That's about all I can think of....
