What makes you think otherwise? 3-3-3 is the standard on almost all carriers operating the 787, aside from a limited few who went with a 2-4-2 cabin. The 787 cabin width is 5.49 Meters compared to 5.87 on the 777, since many carriers operate a 777 with 10 seats per row, 9 seats would be suitable for the 787.
Most people are more than happy to be squeezed in Y if it means lower fares. If someone doesn't like it he/she can pay up for a J seat or a Y+ seat (assuming LY will actually install a proper Y+ seat similar to the J cabin on the 737).
