We don't have many regular conversations anymore with JW's, but the few we do with JW family and an occasional "bump in" don't seem to concentrate on the "generation" aspect, bur rather just the NEARNESS. Any day now. Very, very soon. And isn't that evident by all the fulfillment of the signs ? Wars. Pestilence. (That's a biggie right now.) etc.
Consider too that once a JW gets up there is age where their life is sealed -- that is, no longer any chance of making much of the change in the course they are on -- they have to believe it is near or else admit they will die.
