The same thing occurred to me when I visited two LEGO stores near my area (Toronto, Canada). I went to two of them, one said they would no longer be carrying Bionicle sets at all, the other said they were switching them to online purchase only to make room for other themes. The only sets they had were some of the 2015 sets on clearance. If it's true that they would be making room for the new summer wave of sets, then why were the Uniters/Umarak completely missing from the LEGO store I went to? Seems odd to suddenly transfer sets that literally came out months ago when last year they were still available in-store when the Skull Villains came out in August. I suppose it could be for some other reason....but it's a little disquieting to say the least.
