Kate's Bootrom Exploit Paired with Fusee still requires a PC to launch the payload, and the shorting every time the console reboots/power cycles making it a tethered exploit.
I could be wrong as I have not had confirmation yet from Team Xecuter, but being a long time beta tester (since the 90's) for them, I think its pretty safe to assume that the modchip itself will send the payload through a button cominbation or on/off switch of some sort which will enable it at will to boot from the SD card or extra NAND if thats the route they took. Therefor no computer required. Much better solution IMO.
