Next-Gen Source 2 Engine Spotted In Source Filmmaker

Valvetime has revealed some pretty interesting new information, suggesting that Valve is currently developing the next-generation version of their versatile game engine, the Source Engine. Valvetime states that a member from Facepunch, GameDev, has pointed out that there are some new “Source 2 tools” icons stashed away in the Source Filmmaker files.
Not only that, but Valvetime investigated a little bit and found some interesting lines of code in Source Filmmaker’s file, One of those lines is the following:
”’Return an str with the current engine version.
If key doesn’t doesn’t exist, assume ‘Source’, otherwise invalid — assume next-gen ‘Source 2′.”’
This line of code clearly reveals Valvetime’s assumptions. In addition, there are references to Source, Hybrid, and Source 2 in this file. Valvetime speculates that Hybrid is the base for which Source 2 is sitting on.
There is also a code comment about Half-Life 2: Episode 3 and Alyx:
“‘_CONTENT = None
def content():
returns a Path instance representing the %VCONTENT% path – path construction this way is super easy:
somePropPath = content() / ‘ep3/models/characters/alyx/maya/’
Unfortunately, this doesn’t prove anything for the time being, other than Valve is working on Episode 3 (or was working when they wrote those lines of code in Filmmaker). Naturally, don’t get excited for this third, rumored episode of Half Life 2 just yet.
