To be honest it's now much higher on my radar aswell.
I think a proper higher budget Advance Wars could evolve the series in many areas.
I'm not saying they should make it overrly edgy, turn it into an action game or bank on Waifus and Husbandos like Fire Emblem, it's not like the series ever had much of a japanese audience really.
They didn't seem to know what to do with the series looking at the last game anyway, a remake is a safe bet, but this whole situation is almost worse than them releasing a game that was too different for the OG fans.
