Was going to post that one of the Osborne family members is a member of the forums but I see someone already brought her up. It would make no sense for Disney to remove them. Move them, maybe? Remove them, I see no upside.
Hey gang Tristan here again, thanks for all the kind words about the lights. My wife still gets butterflies before she she's them turned on each year.
And for what it's worth, regarding knowing if the lights will be back in 2015, unfortunately we don't know any dates until they are released by WDW. So we are kind of in the same boat as you all with knowing if they will bring them back in 2015 or not. (Of course if they are to remove them completely I'm sure they would let us know.)
I seem to recall Mitzi (Osborne, my mother in law), saying that when they moved them from residential to SOA they were told about that well in advance since they actually weren't displayed at all that year.
I'll keep you all posted with any info I get as soon as I get it!
