As far as 27.5+.... As far as I can tell, after a correction in the over-enthusiastic bubble, interest in and availabilty of 27.5+ has been remaining pretty consistent for the past few years.
THAT is the reality.
That the above is somehow indicative of them “fading away” - which implies a fate similar to 26 - is conjecture.
Head over to Jenson and filter bikes by wheel size. 29 dominates. As it does on Specialized, Trek and to some degree Giant's website. Giant jumped in with both feet on 27.5 and are gravitating back to 29 on their models now because they realized the mistake. 27.5+ , which was common for 2-3 years, is starting to be replaced by 29 with boost spacing which gives a person the 27.5+ option. Then the manufacture only needs to sell the bike with one wheel option leaving it to the customer to decide if they want 27.5+
My gut feeling is that 27.5 will go the way of 26 in the near future.
