Pretty sure if you come from IG you will have to walk around the Future World side of the lagoon (past UK & Canada, then over to Mexico, then Norway). I was there on 2/10, coming from the main gate, and there was a rope up at the China end of Norway preventing you from going farther into WS.
Note to add: Guests have always been able to enter Epcot via the Intl Gateway at park opening (9 am or AM EMH) to get to Future World.
