Only because you asked, just my opinions, I have no secrets to share:
Tower Bridge probably not going anywhere even if it does, it's very old, many have been accumulated.
Pet Shop probably going this year (hopefully) but again, many have been accumulated, so have patience. I have more than I care to but I got time.
Sydney Opera House would be a good gamble as it's not as old as TB and sometimes more expensive scares off people.
Ewok Village should go this year but it's Star Wars, a little obvious a choice.
Palace Cinema, if it went this year, it would be ahead of trend, so that would be great but don't count on any favors from TLG.
Sandcrawler should go this year and more expensive than EV, so again (as stated above), Star Wars (obvious) but expensive to some.
Santas Workshop should go this year but way too many in hands. This is a waste of funds to me. Yes, I have wasted money here.
Fairground Mixer a gamble as it doesn't seem to sell and maybe done but it'll be awhile before we know as not enough move at retail.
Parisian Restaurant bigger gamble than PC as it's way earlier than trend.
Simpsons House sells better than Kwik-E (last I checked) and older but both should go at the same time. Still a risk to me.
That's all. Good luck.
