Yes! That's right! :-)

We'll have a full featured APT shell for the next release. Some of
it's fetures include:

- Stateful cache. Mark packages as you want and when satisfied with
  the current selection, commit to the system.
  
- Gradual selection. Each time you select a package that will include
  more changes in the cache than was requested, you'll be notified
  about what changes will be made, and given the option to cancel.

- Smart completion. Command line completion for commands, package
  names, and versions. When removing, only installed packages will
  complete. When keeping, only packages selected for changing will
  complete.

- New list/ls command, allowing one to list packages in a confortable
  way, including shell wildcards. Also, options for listing only
  installed packages, only upgradable packages, listing installed
  and candidate versions, and listing summaries. This was inspired
  in The Poldek's counterpart.

- Inline help.

- Very fast.


Here is a long "screenshot" for your pleasure.
