Antonio- sometimes manufacturers have staff that monitor forums for feedback and various other info who may/maynot post........occasionally you get an enthusiast who is also an employee that might be privy to inside info- so it doesn't hurt to ask...........we may just get lucky and get a Pentax insider who has a nickname that isn't traceable to them.
I won't say which- but there was a forum I was a member of and we had a Canon insider that revealed small things- it was awesome as he'd post pending developments that always became as stated- I rarely go on that forum as it's more of a video forum than anything else.....was hoping for the same luck here.
As a side note: Samsung has been using this strategy as of late and has released new firmware for their new top of the line NX1 (something like that) of which was stated they'd been listening to users requests via forums and promises more firmware updates as they really want to be a big player in the mirrorless market which they've recently stated will outsell DSLR's in 3 years!
