Prosser had some inside info on the iPhone SE2, but most of his predictions ever since have been questionable to say the least.
- New AirPods "ready to ship" this spring? Then postponed to WWDC? Still hasn't arrived.
- WWDC hardware predictions - WAY OFF! No hardware whatsoever.
- AirPower - Turned out to be a fake photo! Which he added his own watermark to...
He might have some guy on the inside of the supply chain, so he might be able to predict a release a few days ahead of the official announcement, that's it (MacBook Pro - reported same day, iMac a week ahead). Not sure I'd trust him for an event two months ahead, seeing as his WWDC predictions were so off.
