It's probably just too early in the product lifecycle for a slim model. The PS4 just barely eaked one out at the 2 year mark because the XBone and PS4 were pretty dated hardware when they released, the PS3 took 3 years, PS2 took 5 years The slim "PS One" took 6 years. Capacity for die shrinks is probably a bit tight at the moment given the chip shortages and the fact that Apple are basically buying all TSMC production capacity on stuff that's vaguely new. The 6nm process they've just picked up for the PS5 refresh was coming online when the PS5 was first released. I imagine we'll see a true slim when Sony / AMD are able to get enough capacity on the 5nm or 4nm process.
