No, they don't share anymore. I have been driving the bus now for a year and since I've been there the routes have not included the GF with Co/Po except for Studios.
From DAK, one bus does CO/PO, one does WL/GF and one does FW.
This is the same for DTD with the one exception I wrote about in the previous post.
If you are dining at Rainforest after DAK is closed or leaving the park well after posted closing, routes will be combined.
