Hi all, new Wii U owner here. I've recently started browsing these forums and decided to purchase the console, bought on Ebay. I got the Mario & Luigi Deluxe set and it's currently on 1.0.3U. I've read that 5.3.2 is the one that I want to be on, but other posts have said that earlier firmwares may have better possibilites in the future. Should I hold off and see how things fall or go ahead and update to 5.3.2?
