Yeah, from my point of view, the vast majority of LEGO sales are in the 4th quarter and a large set like the SSD is most likely bought/given as a gift so why would they intentionally plan on EOL'ing a large money-making set in the summer. Makes no sense for LEGO to leave money on the table like that.
I believe LEGO makes plans in the beginning of the year for it to EOL at the end of the year/after Christmas so they produce a quantity of how many they think will last the entire year. Then all of a sudden, they sell out that entire amount in Q2 because of the panic buyers. Well, now since it's Q2, they still have enough time to set up a new production run to make more in time for Q4 sales.
Now, if there wasn't the panic buying and it would then naturally sell out in late Q3, early Q4, LEGO would probably not have enough time to set up a new production run to make Q4 sales so they are just gonna let it go EOL early before the end of the year since there would be no point to make more if sales just plummet after Christmas. So, with all the panic buying and selling out now, it's actually letting LEGO make more in time for Q4.
That's why I'm thinking it will come back to the US, too soon to sell out and still enough time to make more for Q4 sales. If I'm wrong, oh well, still got a couple.
