I don't know why Apple is taking so long with the SE4. With the unsold units (their fault for almost no marketing) they could take the frame for the 12 and 13 mini, do a single camera back, make them all 128GB storage, and maybe put the A14 chip in it. Those would sell super quick. Smaller camera means larger battery. Even at the same size as a mini, more storage, better battery and full front display as big changes over the last version. For people that get the SE, the much large display, great cameras, and 512gb storage aren't the important factors.
