If being in the title sequence means they're a series regular, and thus obligated to all episodes and the next season, then Colton Haynes was, indeed, a series regular, as he was in the title sequence for s1&2.

And if you will notice, Tyler kept saying he doesn't know the plan for Derek. He was avoiding the question posed by doing this, because there are two other Derek's available without him. Young Derek (never can remember his name) and Wolf!Derek. He could have said 'at this point I'm not contracted for any episodes for 5a. But he's playing politics just like Jeff so that more fans don't bail this season because him and Dylan are a huge draw, both together and separately.
