" ... overall enrollment in health savings accounts linked to high-deductible health plans increased almost 12% to nearly 17.4 million this year"
Remarkably, HSA enrollments in large employer plans are up by more than a third over last year. On the other hand, small group and individual enrollments remained flat, but that's not necessarily bad news: for one thing, not losing ground is a net positive for this market segment. And for another, we don't really know, since there's so much confusion in the individual market as to whether or not folks have any insurance in-force.
Anecdotally, I know that I've seen an increased interest in these plans, and my HSA clients who've had to transition to ObamaTax-complaint plans have all requested to stay under the HSA umbrella.
Time will tell, of course.
