RUMOR: Sony A7rV has the As7III heat sink

I have been told the Sony A7rrV will have the same (or similar) heat sink design of the Sony A7sIII. This will allow the A7rV to record 8k videos up to 30minutes.

Sony A7rV specs:

• Same 61MP sensor because all the power goes to the new processor.
• TOTALLY New Autofocus system with AI deep learning
• 8k 24p (cropped)
• 4k60p 4k24p (full read out)
• heat sink design of the Sony A7sIII (up to 30min 8K recording without overheating)
• S cinetone is available
• 8 stop IBIS (unclear yet if “native” or with “gyro data”)
• Body looks like a mix between the Sony A7sIII and Sony A7IV.
