I certainly never bought (and wouldn't consider buying) a camera based on imagined features that may or may not be added sometime in the future.
I simply look at what a camera is capable of at the time it's offered to me, and when I like the deal, I am buying and using it.
For example, I bought all three Sigma Merrills a few weeks after Sigma had announced the Quattro, but I certainly didn't expect Sigma to add Quattro firmware features to those Merrills in the future. Quite the contrary: Now that the successor models are available, I'm pretty sure that Sigma won't add anything new at all to my discontinued Merrills. It would be very bad business. After all, Sigma needs to sell those Quattros now.
That's why I think Fuji is quite customer-friendly by providing feature updates to pretty much all enthusiast models during their lifespan. However, I don't expect them to continue doing so after a model's end-of-life.
And there you go!
