It's beginning to seem as though even Fujifilm is uncertain about the future of its X-Pro camera line-up. Initially, it seemed as though the compact interchangeable lens cameras would be cancelled outright, then leaks and rumors tentatively pointed to a late 2024 launch.
More recently, though, the latest rumours out of Fuji Rumors claim that the X-Pro3's successor (often referred to as the X-Pro5, although X-Pro4 also seems likely) will not be released in 2024 or 2025. That's not to say the X-Pro line-up is cancelled outright, but it wouldn't be surprising to see it cancelled, especially with Fujifilm's renewed focus on the mid-range and upper-mid-range camera markets with the likes of the X-T50 and newly announced X-M5 (curr. $799.95 at Amazon).
Previously, Fujifilm all but confirmed that the X-Pro line-up is still on the table, but it didn't reveal a release timeline, and recently, Fuji Rumors speculated that the X-Pro cameras would be split into two separate camera line-ups, with the rumoured digital X-Pan camera launching as an off-shoot of the pro-sumer X-Pro camera line-up.
It's a bit of an open secret that the X-Pro cameras have never been Fujifilm's most popular X-Mount cameras, largely owing to their niche appeal. They generally offer more or less the same capability and basic hardware as the other X-Mount cameras in Fujifilm's line-up, but they offer a unique form factor and cost significantly more than their stable-mates. The X-Pro line-up has also taken a few hits to its reputation thanks to complaints about scroll wheels and displays that seemed prone to premature failure.
It seems as though the more affordable X-E5 is still on-track for a summer 2025 launch, though, which aligns with Fujifilm's shift to a mass-market strategy. The X-E5 is also expected to bring significant improvements over the X-E4, including the addition of IBIS and a higher-resolution sensor.
