Well, I expect this set to EOL in mid-late 2018. I expect EV and possibly SC to go this year, then Slave I next year. If the TIE retires out of order as with B-Wing, you guys will do great. No argument there. I just don't see the level of unpopularity with this set that B-Wing had (LEGO Shop at Home reviews under 4, for example, vs. 4.6 for TIE), so I'm not seeing the early retirement. There were lots of complaints about 10240 (cockpit stickers notably), and it had the full UCS lifecycle.
I expect UCS or any sets with a 24x20x4 box footprint to provide a $100 after fees return in 1-1.5 years. Otherwise the space is better used for something else. Fire Brigade, HH, TH, B-Wing, R2, and (almost) GE did this. I'm not convinced that a TIE can, if I have to hold it for two years before I can sell (basically, I debit a set that size $30 per year for sitting there and taking up space; PS owes me lots of money at this point).
