Is it available in the UK?
I managed to get a copy from 365games.co.uk. However they now list it as out of stock. I think that was the only place I found which sold it at a reasonable price (£29.99).
So, it was available but I'm not sure how widely.
Maybe you could put a stock alert on 365games.co.uk and hopefully they will get more in? It does seem like everywhere either didn't manage to get it or sold out. Or possibly didn't even receive their stock yet. Either way I'd suggest checking the usual places and placing stock alerts.
