Is there a clear path to a yubikey device supporting 1000+ resident keys and doing so well in the near future?
What does the cost look like? Are we talking $50 or $500?

Additional flash that is just as secure would be expensive mostly because other Smart Card uses don't need it, but it doesn't really have to be secure because storing resident keys could be done in a similar opaque style as a server and only really brought in to the secure context when needed.
Edit- misremembered NXP->STM and added USB as difficulty getting significant flash within the NFC powered chip is an important consideration.
When I bought a (single) Yubikey from their website late last year, it was Fedexed to me directly from their Palo Alto downtown office, not some distribution center in the middle of nowhere. That can't be cheap.
