Full specs for the fp aren't really available yet, so comparison is difficult. There is a bit of confusion about what can be recorded internally vs. externally with future firmware updates muddling the waters a bit more. One feature I really do like is the ability to record to an external SSD through a USB-C connection. Can anyone verify what mode it records to the SSD? I've seen speculation, but nothing verified.
Another difficulty in comparison is from the utilitarian nature of the camera. I think it would be hard to simply take the camera out of the box and start shooting in a productive way. Its form factor almost requires accessories, while the others are capable of working without kitting it out first.
I would be hesitant to get too excited about it until more information comes out. I do think it has potential though.
The students in my high school AV class write and perform a "radio play" as part of their script writing unit. Results vary with my students, but forcing them to remove the visual element emphasized the importance of the various story elements. I'm considering letting them listen to excerpts from the Alien 3 production to help inspire them. Can't wait to hear it myself.
