Skill plate shop question

So we all know this will be the last mlc we see the plate shop so I have a question about it. Will we see other ultimate plates swapped in throughout the month? I ask this because it's 3 feuds this mlc meaning it will be 3 talent ups meaning someone could get a total of 33 plate shop coins. You can get every single thing in the shop for only 29 coins. I ask this because I and I'm sure others have been saving these for months prior waiting for a different ultimate plate to come so have a big abundance of these coins already and I don't want to use 29 of them if we will see other plates swapped in. Maybe previous ultimate plates that have been in the shop?
