If any K1000-like (I'd rather say KX or MX-like) retro camera was to come it wouldn't be a cheap option but an expensive one or at least a 800$, bare minimum.
Les modes, less apparent electronics but nice metal construction and very good VF. That would be something like an MX-like, right?
Too bad, it costs half a kidney in our modern times. I'm the first to be pissed off but at a budget, it just won't come.
I can see though, a retro cam from Pentax but in another alternative body serie. Not in the K500<K50<K5II<K3 scheme.
They could even call it retro-K if they wanted. That would be the body to put the aperture simulator back with a huge VF and a FF sensor
BTW, if you noticed the Sony announcement, look at the sensors: one of'em should be the Pentax FF sensor. So 24Mpix with built-in PDAF or conventionnal AF with 36mpix ?
