There's a very different picture country to country in all things - treating it as 'Europe' is usually wrong.
We also had Lost Grimoire here in the UK a couple of days before the US, PVS and Academy Warlock and Priestess were all very prompt.
The problem we have in the UK, when we have a problem, is not really anything to do with AW. We have one distributor of any size, who more or less have a monopoly, anything below that is more or less shops doing their own importing. So depending on decisions they make, we either get it at all shops or none, enough everywhere or not, get it promptly or months later.
We have a very wide network of online and FLGS, but a bottleneck at the distributor level.
