That's probably not a bad thing, my wallet needs a bit of a break!
You're right though there's nothing in stores that really says "buy me!" at the moment. Sets I think that will do well long term are the three OT Star Wars sets; Cantina, AT-AT and ISD, but these all have a lot of shelf life left in them. Maybe Bennys Spaceship if bought at a discount which might be done by mid-year, that's about it really. Of the remaining in-store exclusives nothing excites me too much, I'm not too confident on the Sea Cow, Ewok Village or Simpsons House, even with 20% off it might take a while after EOL for these to pay a decent return.
Unfortunately the crappy Australian Dollar has taken away many options of bargain buys from the US, which makes life tough for us!
