Headstart.
It helps a lot. NES was dominant before the Master System.
Genesis held off SNES way longer than it should have.
Helped PS1 destroy the N64.
PS2 pretty much had the gen won before the first Xbox or GameCube ever sold.
Gave Dreamcast the "biggest launch ever" at the time.
The Xbox 360 wouldn't have even been an option without a headstart over the PS3.
It's not a guarantee it win the generation (see Wii) but it's better than launching head to head with a platform that could stay all of your thunder. Unless it's going to be undenii better than PS5, they'd better launch first and build a lead.
