According to this DPReview thread, the Nissin Compact Flash i40 isn't expected with TTL support for Fujifilm X cameras until October this year. But with a guide number of 40 at 35mm the i40 appears to provide enough power for the user coming from flash units powered similarly to Nikon's SB700, but in a much smaller package. And thanks to a metal accessory foot and push-button locking pin, it should be more sturdy than Fujifilm's current offerings, while offering similar levels of menu-less operational simplicity.
Both indoor and outdoor shooters may find this especially important. I know I do.
Last week I shot a wine event for the British Embassy here in Tokyo armed with the usual: a D800 and a 50/2 Ai and a 28/2,8 AiS and an X-Pro 1 with the Voigtlander 12mm and the Fujifilm X-T1 as backup to the D800. My flashes were Nikon's old SB28 and current mid-level SB700. Both Nikon flash units were too top-heavy, pitching both the X-Pro 1 and X-T1 forward when hung on a camera strap. And of course, neither shot TTL. Why I've not invested in Fujfilm's flashes can't be answered in a small article. Suffice it to say that I'm reticent to invest fully in a system that still hasn't proved its longevity. Hence my sticking by my Nikon guns. Any modern flash will work with X cameras manual mode, of course at poor sync speeds. But I'm itching for TTL ease of use. And again, I see no comparably sturdy flashes from Fujifilm. I've destroyed three plastic-foot flashes in the last couple of years.
I am very much looking forward to this flash unit. If indeed it debuts in October, Ω will be taking a close look at its performance in event photography.

Fuji VS Fuji have it right. If ~35mm full frame is the next logical step in iterating the X series, it is an important one. If you are a dyed-in-the-wood APS-C fan, you already have what you need. Stifling innovation with "FF no-no" helps no one.
It is refreshing when the photographer gets in the way of the technology, and creates something refreshing. DPReview reader, tolleknolle, tricks out the Fujifilm forums with a handful of soft, atmospheric IR photography which split from the norm. They just happen to be taken with a Fujifilm X-A1. And, they are worth a peak.
