"2016-08-08: I post about the FCC filings, the short-term confidentiality, and a JOKE about Vita 2.
2016-08-09: Some Japanese website uses these two patents to start a Vita 2 rumor.
2016-08-10: GAF rumor starts about Vita Trinity. Musing about the modules part numbers.
I was joking about Vita, this is the Neo thread, they already announced Neo. So the most probable is either Neo, or PS4 slim, or even a simple PS4 revision. They also have a USB wireless module coming.
The short-term confidentiality letter is always there on all their patents, I mentioned it to point out who signed it, and it indicates the time frame for product announcement. The important part of this letter is the signature, it makes sure this is an SCE product, because SCE files everything under the generic Sony Corp (the FCC prefix AK8), making searching patents difficult.
Those part numbers mean nothing. All wireless modules by SCE are J20H0xx for the last 10 years.
When they source complete modules it's usually AW-xxxxx (AzureWave) and there's a million of those."
And many of the newest comments at gaf arent looking so bright.
