Ah, that's the rub ... you consider the style and retro look to be "pretending". Well, that's a reasonable conclusion, though I don't share it. But that Bluetooth handset ... oh yeah, I got to have one!
I think the deal with this new Fuji is that they likely wanted to produce something truly compact, hence the somewhat silly reference as "portable" in the press release. Making it a folder is the only way to do that with a film body. So interchangeable lenses is out, you just can;t do it (I don't think) with a folder and keep it compact; that would be view camera territory, which isn't portable in this sense.
I doubt there will be a system RF line introduced after this, but who knows.
The central thing is, to me, that the company is still Fujifilm. They refuse to delete film from the corporate identity. And seeing a market opportunity which will drive the sale of 120 film (with its higher profit margin than 35mm packaging), they are testing the waters. Whether they actually produce this camera or not, it's refreshing to see them floating the idea. And if they do produce it, I wouldn't be surprised to see the lens in f2.8 incarnation, plus two versions: SC and EBC.
