One of the things that attracts me to Pentax is that the body kind of is future-proof as the K-mount is probably going to be here for a long time. Maybe an auto-focus drive method won't be available, like how some of the newest AF lenses won't have functioning AF if I still had my old K100D, but a body purchase once a decade would deal with that.
Put another way, I don't think a K-50 is going to be functionally limited for quite a while, and at ~$300 or less new I bet most folks would shrug and move on. That said, investing in good glass is probably a more future-proof plan, as you stated. I just wouldn't try to dismiss the want of the original poster of this thread.
