”SOCOM Technologies" is a marketing & advertising firm with no physical address that I can find: https://www.linkedin.com/company/socom-technologies/

Although I would love to hear about a new SOCOM being announced, I think the "SOCOM Technologies" hype is simply a marketing company helping Santa Monica with the circulation of job listings through various job boards aka "ladders". And one of the companies promoting it unfortunately has an interesting name when it comes to SOCOM fans.

The url leading to PlayStation's site looks like a simple search tag of the said company with its placement on the website being in the same area as a link to PS forums. I think people are seeing what they want to see here instead of using a little logic.

Add in the timing of the PSX rumor and I fear this one has been blown way out of proportion and we will all be disappointed again come early December.

So most likely nothing of interest, except maybe The Last of Us 2 gameplay, but then again won't be like it will be massively different from the first. Pretty disappointing although we might see some cool third party announcements.

I don't see suckerpunch studios unfortunately.

I don't think it's the complete list. There is a rumour that a new SOCOM is in the works but as of now it's just a rumour.
