I wonder when that's going to get old. On an odd note, they did deny "source 2" to ever exist until recently. So, I guess there is hope for you.
Developing the engine (even if it is mostly incremental enhancments from the games released over the years) must have taken up signifficant resources lately. If the engine is "done" now, there should be people available to work on new titles.
Chances are, they are developing the engine alongside a new game built on that engine. That is after-all how most game engines are built.
That would be the "mostly incremental enhancments from the games released".
Releasing something publicly makes a huge difference.

At least people can't make Duke Nukem Forever jokes any more.
I don't think Source 2 was a surprise to many. Most of the people in the Dota 2 and CS:GO communities have been expecting it for a long time. Valve even explicitly stated[1] in early December that they planned "a major improvement to Dota 2’s engine that [they] are aiming to release in the first half of next year"
Well, when they announced a press release for 3/3 at 3 PM, I was certain it would be about Half-Life 3.
At GDC? No way.
Maybe it will be a demonstration title running on SteamOS and SteamVR using Vulkan. I dunno, but they would probably want it to be special and pilot some new cool games feature.
