Yes, maybe for this season, but i'm sure that Hokage Minato will show up once again after some months .. Since giving way to other upcoming new ninjas have more priority than releasing old ninjas in events repeatedly .. How can i put this into simple explanation? .. hmmm .. Let's say in Anime, The plot story is the Whole Game where New Characters constantly showing every season, but to make a break for this story, they put some episode which is about the side stories of previous episode, and that is what we call the "Fillers" which we can compare to the Old Ninjas ..

Hahahaha .. It's ok bro, Hokage Minato is a great ninja and one of the superior ninjas in the game right now ..

wahahaha! xD .. no, i didn't mean that, what i mean is the appearance of Old Ninjas in the Events such as Minato Hokage, that maybe this is the last time for this time we will see him in an event and after releasing new ninjas, it will take a break and Minato show once again .. :p

Lol xD .. Minato can't get you out of Hospital if it happens you got some accident nor give you shelter if your house got toasted .. Don't encourage people to spend their life savings in this kind of things, virtual things .. Not all people in here can differentiate the important things from not .. Your message can end up reading by some child here and makes a move to spend his college fund or secretly takes his parent's cards and make a purchase just to buy that Minato ..
