Way too early to call. It's likely not even the same situation. Despite how some people may want to view it, Awakening's "protagonist trio" is treated far from evenly.
Chrom is, at the end of the day, the main protagonist. Not Robin, definitely not Lucina, but Chrom. Lucina is a lord in name only, despite what her class says. From a gameplay perspective, she is not ever a forced deployment and her death doesn't prompt a Game Over. Robin is in the same avatar pseudo-main lord category Kris was in. Death prompts a game over, but is only a forced deployment during certain pivotal maps. Robin has the added benefit of having final segment of the game partially revolve around them, while Kris just had the paralogue chapters and prologue. But Chrom? The first two of the three acts revolve nigh exclusively around him, and the final act is split between him and Robin. When what effectively amounts to 5/6 of the game revolves around him while the final sixth is Robin's, I literally don't understand why some people act like they're equally the main lords.
Robin and Lucina are protagonists, but Chrom is the main protagonist.
