Ubercart is not becoming drupal commerce. They are totally separate projects. Development on Ubercart is and will continue.
Ubercart has not been abandoned. Several people (myself, Lyle - 3.x maintainer, Andy, Mahitha) are all still dedicated, and backed by full-time employment, working on Ubercart and future improvements, and will be for the forseeable future-4.x and beyond.
But the real strength of any open source project is the community around it, so download the alpha, test it, report back, and continute to develop on Ubercart. You can be certain others are doing the same.
