The new software, called “click packages” would allow one to install self contained apps that would not have any dependency requirements. So, it seems like that they may doing something similar to the system Mac OS uses. The base system and apps will still be installed using apt/dpkg, so Canonical is not abandoning apt/dpkg altogether.
It should be noted that Canonical has been shaking up the Linux distro scene lately with some pretty big changes to the Linux desktop in a while. They are planning to abandon the X windows systems with a replacement that will run on mobile devices (phones and tablets) and desktop computers. Their Unity desktop environment is also unique among the other Linux distros. As you can imagine, there are some who are not fond of the changes Canonical are making.
