Personally I don't consider these 'Star Wars' figures, as I don't SOTE or EU. So I wont be looking for them. But for kids they look pretty cool. I can imagine a kid being bored quickly with Luminara types (statues) but being impressed with these. They are totally aimed at kids and I'm sure those are the ones who will appreciate them.
For the 500th how about a nice delux Darth Maul J/K of course. I would love to see a decent Jabba, that would make a nice 500th in a nice box with dais. I know it has been rumoured but I wont believe it until I see it.
They look absolutely excellent. They are a bit pricey in the UK approx £15 each+ postage. An extra £5 each, more than when the 25th anniversaries came out. I don't know wether the base is worth a fiver or not but I will hopefully get them. They will look cool next to the 25th's.
