I've read they're unifying the cross-platform development, which *can* certainly be a good thing. However I really hope they won't use Electron or some other bloated framework for this. I've tried Nimbus Notes which uses Electron for their "native" Mac client. It uses 750 MB of memory (...). I refuse to use bloated apps. That would be a huge motivation to look further.
I really like Evernote. For me it's the best note app I know; believe me I've tried them all. I really hope it will stay a real native app for every platform.
