I, for one, won't buy these packs in any near future. Simply because I'm satisfied with the core game and do not see any need to spend 16€ in those packs.
I'm sure they are nice, but with the offline-only ships the only attractive thing left are the new tracks (because why should you learn to handle those ships if you can't race them in multiplayer anyway?).
And right at the moment those are no 16€ worth IMO. Maybe in a few months or something
