since it has been asked in many forms quite a bit, here is a slightly updated path.
1) All console models should be supported for some things, such as Flash Dump, IDPS Extraction, using root lv2 syscalls....and a few others.
2) We have ran into a few issues concerning 300x and 4xxx consoles as far as writing to flash with lv0.2. These models will most likely require another exploit to take full advantage of CFW features like older consoles, and may not have full support upon release. These models may need the community to build upon our current work....this is not fully worked out yet and may be resolved.
no promise on release date, but x-mas is a good goal for now
