Well, one thing is for sure, it'll never get better.
It's hard to say how much worse ghosting can get, as it varies from game to game. Some games will continue to get worse over time to the point of clearcoat cracking over inserts and inserts sinking or lifting. Other games will just show the ghosting on the inserts, but they'll stay level. It's a cause for concern, but it can be addressed if things start to get bad.
