We weren't happy with the time tracking integration in Classic. It was usable, but it wasn't great. We want to take our time to either come up with a better built-in solution or an integration with another tool or something else.

This is a big part of why we're keeping Basecamp Classic around for a very long time. Basecamp Next was not going to launch with all the features that Classic already has. So it's OK that it's not a perfect fit for all existing customers on Day 1.

The iPhone didn't have copy'n'paste for a while, either. There's just so much you can do for launch, if you want to ship.
