There is currently no FCC filing for this, but there does seem to be evidence that Polar will launch the M430 on Thursday. This is significant since the M400 and V800 both launched very close together, so this gives hope that the v830 is just around the corner. Yes, I said v830 with no evidence, why not, the name M430 seems completely arbitrary to me so I’ve matched it 🙂
As ever appelmoessite is on the story. No idea who the source is there but it seems a good one.
