Then just a couple of weeks ago, Oppo’s Ultra model was back on. Now, it’s apparently off again according to a prominent leaker.
Digital Chat Station has said, slightly cryptically, that “Another ultra-sized cup has changed; the project is currently suspended.”

It’s machine translated from Chinese, but you get the idea and it’s the Oppo Find X10 Ultra he’s talking about here. Oddly enough, it was also Digital Chat Station leaking details of the camera specs just a matter of days ago.
There are a few possibilities as to what’s going on here. The first is that we’re getting something close to a fly on the wall insight into Oppo’s planning and development process in almost real-time.
Plenty of tech companies will make products which never see the light of day, and with ‘Ramageddon’ causing havoc to the BOM (bill of materials) to make phones and other devices, it’s harder than ever for them to figure out whether a particular model is going to be successful.
It’s also possible Digital Chat Station, though historically reliable, is inflating small details into something bigger than it really is. He could also just be plain wrong; All leaks should be taken with a pinch of salt, no matter who they are from.
