Though lacking in specificity the fact of downloadable upgrades (for a fee) is mentioned in the 2014 tech bulletin.
Updates for my F-350 and my wife's MKX are both around $200. Never did and never planned to update either, they both work fine.
As for new roads

I have pretty much figured out, from using portable GPS units for over 10 years now that that it takes about 10 years for a new road to show up on the database. Especially if it was never a paper street.
I think it was last year that Kathy, Brian and I were on a highway for 5 miles or so that didn't show up on either of the GPS's
I have the lifetime update for my Garmin ($99) and it is such a pain that I only update about once a year instead of the offered 4 times a year.
And to boot, the data got so bloated last year I was back to only having regions stored on the unit instead of the entire US.
