I think we shouldn't confuse interest in an item and qfll potential. Yes this set is highly anticipated in UK, however there will only be qfll potential if ALL shops sell out (SAH + supermarkets + independent B&M shops + TRU etc). People have already started to undercut each other on ebay and are selling for £59.99 + postage in uk. The real money was made by the people who managed to get this set from lego liverpool last week.
You can make money if bought from tesco 3 for 2, however the amount of money is not alot considering the set is only selling for £60 shipped, after p&p / fees etc you end up with not alot.
The only reason technic porsche did good was it was only available from lego stores in person, as all SAH orders were delayed for 1 month + no other store except lego sold it for first 1/2 months.
This set is NOT exclusive to Lego, so is not limited at all.
