I use Twicca (great mobile app for Twitter) on my Android phone and they pushed a notification about this last week. They will be updating to support the new Twitter, but warned that the timeline may not be available, or something to that affect.

Not sure if they aren't able to support changes to the new timeline, or that Twitter won't let them, or that the timeline will disappear completely. Guess we'll find out.
