To look at this from a different angle, there is a saying I truly believe in and apply it to quite a few situations in life.
"I am prepared for the worst but hope for the best" Benjamin Disraeli
If this is EOL or close to it for the Town Hall, it will be a good thing that many people believe it isn't the EOL. Quite a small percentage of us are panic buying, myself included. On the other hand, if we are far from EOL, then some of us will have hit our quota far before EOL and when the end does actually come around, again there will be less panic buying since most will have already hit their mark. So I say believers, keep buying. Let them collect dust if we're wrong because you won't have to worry about this set down the road if you can keep some money tied up now.
On a related note,quite a few BPs seem to believe that when we go on a panic buy in these situations, LEGO produces more to screw with us specifically. I work in a manufacturing environment and for people to think LEGO just switches gears on the spot to pump out more sets because there is a sudden surge in sales due to resellers is plain ludicrous. The cost of manpower with change over, setting up new jobs, and completely changing of manufacturing schedules is a lot of money lost, especially at this scale. Is it possible that they do it? Yes, but probably not to mess with resellers but because the scheduled life span of the set hasn't been reached and they need to replenish. Can they change their mind when the end of life of a set is? Of course but it would probably be due to how the product sells over time and not sudden spikes at 2xVIP days etc. More than likely, they are regimented in staying true to the schedule of a sets lifespan, and only a handful are altered due to demand. The RI and DS are pretty good examples. I know the DS is licensed and one of the biggest/most expensive sets ever but they keep extending its life probably because it sells well. The RI is unlicensed and one of the cheapest sets to buy yet they have seem to keep this one very limited (so far) even though, and I'm sure TLG are aware, resellers are the ones poofing it whenever it pops up. There will probably be one maybe two more runs of this set but demand will still exceed supply in the long run.
DISCLAIMER: The last paragraph is just my opinion, no facts but it is drawn from years of experience in this industry. So rip it apart!!
