They've promised big things before, and never followed suit.
I hate to keep bringing it up, but it's the best example: A Nokia dev said, on his official S60 blog, that they had a browser update ready to go for the first generation S60 browser devices (S60V3), all they needed was marketing's approval to get it released.
Marketing never approved it. Why should they? If they update the browser and other components of an older handset, why would anyone bother to buy a new one?
So, no... Nokia gets no benefit of any doubt. It's long past time for Nokia to just shut up and put up, in that order.
