I don't see those happening. Just my point of view, why would anyone have a subscription at that point? If you just buy unlocks that will unlock the entire game, you would unsub. I think they need to keep those things in place, give the people who sub a feeling that it is worth it for them too sub.
They can implement new things to motivate people to subscribe while giving the F2P players a non broken game. Like the credit cap that really benefits no one because it prevents the F2P from buying stuff they want from the GTN and Subscribers are forced to undervalue items because the Sub market is much smaller then the F2P market. But with the changes to travel prices and such they could keep them the way they are now for Free players and greatly reduce the prices for Subscribers.
