They are not behind. Since they are not trying to catch up with Sony or MS. They purposely choose to use cheaper hardware and go a different direction. That’s not the same as being behind.
It’s their Blue Ocean strategy. They don’t want to compete directly against Sony and a trillion dollar company called Microsoft. Since the last time they did that it almost took the company under. They make a profit on each Switch sale since the first one was sold and they offer an entirely different gaming catalog that targets a different audience.
The dude was talking about the antagonist and not the playable character. That’s why the playable character says “She’s back” at the end. Also it was just a teaser trailer to remind us that the game still exist and to show some gameplay. It was definitely not a commercial to sell the game to us. The development is probably no where near finished.
