The Apple event theme is "Time Flies" so I expect it will be about a new watch. Rumors are that there may also be a new ipad or two. It's possible they could be doing something related to fitness which would be interesting. Peloton CEO John Foley is a big Apple fan and has called Peloton the Apple of the fitness industry.
Didn't seem to be much related to Peloton in the Apple event. In fact, the Fitness+ service they announced will compete with Peloton - especially Peloton Digital. Will be interesting to see if Apple gets into making bikes, treads, rowers, etc.
