A clip showcasing Final Fantasy Crystal Chronicles: The Crystal Bearers was not included with the Wii version of Echoes of Time in the US. That doesn’t mean Square Enix won’t release the Crystal Bearers overseas.
Out of the ether, a teaser site popped up with the same Final Fantasy Crystal Chronicles: The Crystal Bearers trailer previously released in Japan. A menu asking users to select region and clocks for Barcelona, Tokyo, and Dallas at the very least imply the game will get an international release. The teaser site probably means more Crystal Bearers news is coming, but not necessarily that the game will come out soon. Square Enix opened sites for Saga 2, Blood of Bahamut, and Final Fantasy XIII months ago. None of these games have concrete release dates.
