The beauty of an open add-on system like OpenTTD is that if you see something that's missing, you can make your own add-on. With enough drive and patience, anyone can learn to create a vehicle NewGRF.
Dutch Set version 2, UK Renewal Set 3.04 (and its addon pack), US Train Set, eGRVTS, NUTS, av8, 2cc train set, and probably some more, do offer some future (relative to 2016) vehicles. Modern Maglev Trains, as name implies, is dedicated to maglev trains, including some future trains.
