Late 5498-SA - what to expect

Greetings; This past year was the first year I've had an HSA, and the site's tax forms page it notes that they will make available the 5498-SA form on 05/09, of course after the filing deadline. I haven't used any funds from the HSA, so I wouldn't expect any tax implications from it. Should I expect to have to file for an extension or will only reporting the information from the W-2 be likely to be sufficient?
