The LEGO Group has a long held practice of releasing LEGO sets for a period of two to three years, then discontinuing them, with occasional exceptions. According to a new rumour from Stone Wars, there’s about to be exceptions made for 21313 Ship in a Bottle and 21309 NASA Apollo Saturn V.
It’s a surprising move given that LEGO Ideas sets often have shorter lifespans than regular retail sets, although the length of time sets have been available has varied wildly in the past few years. 21309 NASA Apollo Saturn V was a particularly popular set, that spent a long time out of stock, and attracted mainstream media attention.
These sets will seemingly be reissues, but in such instances small changes are sometimes made usually as a result of certain elements being retired or replaced.
Rumours should be take with a pinch of salt until official announcements are made by the LEGO Group.
