It's doubtful because LEGO wouldn't just cut such a large portion of a VERY POPULAR theme in one go. (Obviously, I don't have facts on sales but it's hard to believe otherwise) They probably won't retire half the sets we are discussing. Come on people - T1 Camper, Sopwith Camel, GE, TH, HH, PS, Orthanc, etc. all in the same few months?? Unless LEGO is attempting to alienate their AFOL community and piss off a portion of the TFOL population who are saving up for pricier sets, I'm pretty sure we can expect 3 from the list that I just named tops. The odds of all of the sets being modulars is pretty low at that. Several experienced members (as well as some with insider information), have given their opinions, and the arrows definitely don't point to three modulars.
