Have you been to Asia recently? They are very happy with huge screen phones, but the 6.4-inch screen has a footprint similar to that of an iPhone 7 plus or Nexus 6P.
It's not on sale here because we're not such big fans (hence why the Note's never sold in huge numbers here, and why last year Samsung didn't even bring out the Note 5 in the UK), but I know people will import it. And the Mi Note 2 looks good too.
There's still stock of the Pixel if you shop around. Currys / Carphone Warehouse have 32GB models, and the Store gets new deliveries regularly.
The 128GB Pixel XL is the one in short supply, and I was told last week that in (now) under two weeks, there will be a more delivered - possibly sooner.
I think the rush on 128GB models is because initial sales are more likely to early adopters and tech nerds, but coming up to Christmas, when stock is no longer an issue, I expect the 32GB model will be the bigger seller. For one, it's obviously cheaper. Secondly, unless you want to store loads of media for offline viewing (which can be to a degree done with a USB-C flash drive), you can probably get by with 32GB (or nearer 25GB in reality) if you enable the automatic backup/delete feature.
