Of course you can expect that. Expectations are free, even Great ones. (OK, so I read a book once.)
But buyers are chasing sensitivity the way they are/were chasing MP. If I were Pentax, I'd want to keep the NR upgrade to the next sensor/body upgrade. It's a big deal to many and would likely drive a good share of the sales.
And please take note of the word "free" in the title of this post. As I've noted elsewhere, I think there's an additional revenue stream in paid-for enhancements if Pentax can work out the mechanics and the numbers work re: new body sales.
But if NR SW is based on or optimized for the particular sensor (can someone help me understand this relation?), Pentax may not want to develop two code streams - one for the new sensor type and another for the older model.
