Yeah, launch seems pretty fucked here in Australia as well. Aside from online (overseas, nonetheless) it's fucking impossible to find a copy of the game anywhere here except at EB, where of course it's at full price. No ads anywhere, fuck-all instore promotions and, well, I'd talk about how they don't advertise any new features but as I said, there are no advertisements at all.
On the other hand, plenty of copies of the new GH around (with bundles or without) and fucking heaps of promos for DJ Hero 2.
I don't know who's handling it here (EA?) but it seems the franchise has been pretty much sent to die. If people knew they could play keytar with Huey Lewis, they'd sell a million copies, but people know shit.
