I have tried to ask the North American Asus Team about version/model differences. To no avail my only resource is unverified 3rd party sources. Is there a specific North American version being released? If there is a North American version what if any differences would it have to the Global ROM version A? Does the Global ROM version A support all of the the listed 4G/5G bands shown on the website? If I purchased the Global ROM through a 3rd party would ASUS still cover the warranty and any repairs needed in the future? Finally where would the accessories be available at?
