scroll down a little it says driver 5, now i don't know if this is false but gamesradar might have a rough date.

Possibly...But then where is the official content on game spot?

There hasn’t been any announcements to suggest any new Driver game, should that change I will let you know but as it stands no, sorry

Will these be in stickies?

I assume it would be a sticky.
And there is lots of evidence of a new driver title.

That
- Ubisoft Reflections Interview with BBC
- Ubisoft Reflections Employees putting it on their CV.
- Ubisoft Reflections HR is employing employers in the fields driver focuses on. (This could mean Reflections are working on driving game but two points above suggest Ubisoft Reflections are working on a New Driver Title)
