As I was reading yesterday that the 2nd season will start in July, particularly in the My Hero Academia timeslot, something seemed a bit off to me, in particular because I didn't think My Hero Academia would be a short series (but who knows).

Anyways, just now a new article came up mentioning that the Arslan 2nd season will have only 8 episodes:

The June issue of Kodansha's Bessatsu Shōnen Magazine is revealing on Monday that the Arslan Senki: Fūjin Ranbu (The Heroic Legend of Arslan: Dust Storm Dance) television anime series will premiere on MBS and TBS on July 3, and the series will have eight episodes.

The new season will air on Sundays at 5 p.m. on MBS and TBS, which is the "Nichigo" timeslot. The staff had announced in March that the new series would premiere in the timeslot in July. My Hero Academia began airing in the timeslot in April, and The Seven Deadly Sins: Signs of holy war special will air for four weeks in the timeslot starting in August.

Something is still not adding up for My Hero Academia for me at the moment (unless it's moving to another timeslot or if it'll have another season at another point), but I find it curious that Arslan is only getting 8 episodes for a second season.

Of course, I don't know how long of a story Arslan has to tell and pretty much all the major pieces are about to converge as it is, so maybe that's all they'll need to finish it all up. Just found it a bit weird to have this short of a second series, then of course the positive is that they didn't stretch the story to a normal cour needlessly.
