It will get Nokia Drive we can be sure of that (all WP8 phones are getting Nokia drive) as for everything else it will depend if Nokia has a timed exclusivity or just full exclusivity.
In the case of games it's most likely going to be timed, Nokia gets a few months then it's for everyone. In the case of full exclusivity like Nokia services (think maps, and it's camera lenses) then these will always be Nokia only.
