Sorry, but this is the user-to-user forum. You are not talking to Apple here. Nobody here can tell you if or when a camera model will be supported by Apple at all, not all cameras do get RAW support.
All currently supported cameras are on this list: Digital camera RAW formats supported by iOS 15, iPadOS 15, and macOS Monterey - Apple Support
RAW Support is provided by iOS on the iPhone only for third-party applications: "These RAW formats offer greater image-editing flexibility on iOS and iPadOS using third-party apps that support RAW. ... RAW processing on iOS or iPadOS with third-party apps is available on iPhone 6 or later, iPad Pro (all models), iPad mini 4 or later, iPad Air 2 or later, and iPod touch (6th generation) or later."
If you set the camera to shoot JPEG or TIFF the iPhone should be able to work with the files
