LEGO S/H buying limits: Why is Tower of Orthanc limited to 2?

I seem to recall Helm's Deep being limited to 1 per person towards the end of last year, and clearly that was retired. I was looking through S/**** and really all of the exclusive sets have a limit of 5, except for ToO and Maersk ship, which have a limit of 2. The ship is new, so I understand that, but ToO is essentially a year old now. Could this be suggestive of low stock, and possible EOL at the end of the year?
