So? They deserve the money. For doing what they’ve done and for the price - It’s amazing. Nobody is asking you to fork out if the new update comes next month, but if you want the features, pay the fee. They haven’t even said it’ll be out on the 24th, it should be out earlier, You can download it on Git already.
If it was a Marketing move, who cares? Epic have done the Gamedev world a favor that will change the scene as we know it, and if they’re asking for an extra $19 for an update? They deserve it. Especially with the amount of work going into the update.
