There weren't very many at all, but of what there were of new introductions, for me it's the SLSA MVP AERO. A look-a-like Icon flying boat but with appreciable airframe differences and very novel and cool built in adventure flying features.
Took me a while to find it, but when I did, I knew it could be a winner. Glasair is the manufacturer and some notable aviation people are attached to the development so definitely has credibility. They say deliveries in 5 years which is also credible. Unfortunately, they're taking deposits.
I of course implored them to ensure that it would have in-cockpit push of a button wing fold. In speaking with the 2 reps and with a big crowd salivating around the full scale mock-up at the seaplane base, I made sure everyone knew about the dirty little secret of flying boats.
