While that really looks too good to be true, the reality in the current market as of today is that anything which is not a Canon C-series of a BMCC is going for the price of a couple of bananas. The FS100 is basically "free" already. The F3 is going for the price of two bananas and a tomato. Saw some bodies going for the price of this one (although without the lenses) and even "older" bigger full sized high-end cameras are going for less than a new C300. Lots of REDs, specially Scarlet and RED ONE going for cheap too. It's the market reality we live in today. RED came and kicked the door wide open on the cheapness. Others had to play catch and drop their prices. Then RED releases more updates to sensors than teenagers change their minds about what they want to be when the grow up. So the other manufacturers had to again play catch up and release more frequent updates. The result is quicker depreciation of prior models. We get it cheaper and faster, but we also lose more money on the sale later. Can't have it both ways. And it will only get worse, much worse.
Guys, buy those used F3's now while you can... the new F's will not be fully functional in feature set until around September and even later for 4k S&Q functions, LUTS,
The F3 may very well be back from the dead!
Or wait a year and buy the f5 for 5-6k when it is inevitably dumped.
