This will only be targeted in US, no? I doubt it's GDPR compliant and won't probably buyers outside of US. If it's $3500, then in Europe, it will be around $5000.
What’s the issue with GDPR? If it is similar to other Apple products where data is collected / processed at the edge, then no more issues than anything else they do.
I don't think GDPR is a problem, but they might have to cut some features in some EU countries where facial recognition is illegal (if they use that, but they probably do).
Kind of like Google Photos which has facial recognition and tagging, except in the EU.
