Syphon Filter was different to me, because stealth was good, and some stages required it, but others were more like an action film and you could blast your way out. And you took on crazy battles, like in 2 you fight along a moving train and then battle a helicopter as the train careens towards broken bridge, its absurd, so is the virus plot.
And in 2 you return to the museum from the first game but at night and sneaking in, and then fight in a Russian disco club, and then you go back to the first street from the first game and you beat the last guy by shotgun blasting him in his body armor into the rotating blades of a helicopter.
And 3 is all a flashback and there's a hott mission to start the game where you fight through a hotel and then you go to Afghanistan and then you gotta invade the Senate.
All from the guys who developed Bubsy 3D.

In addition to this, a few months ago a Reddit user that went by the name /u/athey mentioned some possibilities that may have occurred at the studio.
On the topic of a new Syphon Filter game (s)he said
Hah. No. Don’t hold your breath on that one.

In addition to this, /u/athey talked about previous projects that have been canned at the studio that range from a inFamous Vita title to new IPs.
It was going to be another Uncharted game but naughty dog was worried about franchise burnout with so many games coming out so close together, so they nixed it. We spent like a whole year dicking around with different ideas and pitches after that before I left the studio. We started and threw away so many demos during that year.
We did a couple new IP pitches. One was steampunk but that didn’t make it very far. There was a really awesome futuristic sci if one that I really liked. We had an amazing future scifi city and a character that could run around and scale buildings with these jet boots, and it was awesome. We had a lot of assets done for that demo when it was canned. I was really bummed when that one got binned.
JET BOOTS. Could call it SYPHON FILTER: 2020: THE FINAL FIGHT.
