Sellest: "Can you run that by me again?"
I'll humor you. While sets often have end dates, depending on their popularity (and profit margins) LEGO will sometimes run them for years past their end date. End dates are not set in stone, especially for modulars, and other adult focused content such as UCS. Both Death Stars ran for years. (And no, I'm not counting Death Star 2, just both versions of the original death star.)
Market Street and a couple other original modulars ran for years. In fact, when I checked last year, Market Street was still on sale on shop.lego.com/en-us/.
End dates aren't always solid. 2006ish Clone Trooper Battle Pack ran for ages, from what I recall.
Also the bit about "Lego is the plural" is kind've elitest. Like a bunch of people talking peacefully about Torghast, only to have @
zyko or his buddy show up with their inflated egos acting like only what they think/know is valid.
