This all becomes effective in December from xingwang's blog

 Today, Psyonix uncovered the substitution for cases. It's a plan framework that gets rid of any vulnerability to Rocket League Items precisely what the player is buying. 

Here's the means by which it works: After certain matches, plans will arbitrarily drop - simply like cases drop now. That plan will highlight a thing that can be created (finished with an opportunity to be confirmed, painted, and so on.) If the player needs to make it, they go through genuine cash for in-game credits to buy the thing. Psyonix hasn't recorded the costs of things, however more uncommon diagrams (like an underground market objective blast, for instance) will cost more than the more normal plans. It's additionally obscure whether individual ascribes, similar to a thing being painted, will raise the cost. 

This all becomes effective in December. At the point when the update goes live, any cases in a player's stock will be supplanted by an irregular diagram. Any outstanding keys (the current genuine cash money) will be changed over to credits - in spite of the fact that the www.lolga.com transformation rate hasn't been reported.
