CodeIgniter 2.0

What will become the 1.7 branch when 2.0 will come ?
Will maintenance stay available for those branch or every team effort will go to the new version.
In such a case appear, one who started project with 1.7.x and who have bug will stay alone and will be forced to move to 2.0
Moving a product (and there will be a huge stuff to move it and test it) is somewhat difficult and time consuming.
It is not silly to consider all perspectives before starting a project of several month of development.
In your response you don't give any hints about those perspectives (maintenance ...)
