My first post...
I have multiple sources that the sets listed below will retire this year.
Got my information from:
LEGO Customer Service, a trustworthy guy who has worked with LEGO for 10 years, famous german LEGO blogs like Stonewars or Brickstory
10243 Parisian Restaurant
10254 WHT
21309 Apollo
70620 NC
21313 SIAB
76105 Hulkbuster
21314 TL
75181 Y-Wing
21311 Voltron
75222 CC
21315 Pop Up Book
80103 (already gone!)
Maybe:
71040 Disney Castle
The castle was marked to retire in July this year, but they changed it. No specific date given. Could retire this winter, I doubt it though.
Many other sets I listed are unlikely to retire in my opinion, like the Saturn V, but that's what !all! my sources told me!
