So I signed up for this, this discounted version was pretty much the right price point for me. Only thing I'd note they don't use/take Paypal. I had to provide a real credit card. Not sure exactly how the account issues will work. Download speeds are really good, appears to be using Amazon AWS (I have 150mb FiOS).
The plugin isn't available yet (not even sure I'd use it) but you can browse/download sounds/packs directly. Right now there are about 288ish packs/products up(very rough count), it is not everything from Samplephonics but is a lot of stuff.
The downloads are only the WAV versions, which is kind of disappointing. I know they have Acidized versions of some things for sale but they don't seem to be part of Noiiz. They do seem to have Sample Instruments included but all they seem to be is "load the loop into the sampler" type instruments. Everything is uncompressed WAV files. Kind of sad the world doesn't support some sort of lossless compression for WAV files. Nothing ever caught on there though.
In the 90's the old monthly Sonic Foundry Acid loop subscription was a one of the few things I loved. I really enjoyed the surprise element of each monthly release, back when downloads weren't even an option. I don't use loops all that much anymore, I've moved on more to instruments, but I still enjoy mixing up loops. So this seemed worth trying.
I kind of hope they adopt a bit more Netflix-like model. Where new materials are made available every month (and even some material being removed). I don't think they have said anything specific though about how exactly they plan to keep it interesting. I tried Splice (another service like this) for a bit, but the credit-based limit was a more hassle than I wanted. I spent way too much time trying to optimize my credits and not enough time using what I downloaded. Noiiz seems to avoid that. I'm looking forward to how it evolves in the next year.
