The limits that bugged it from 2003, are still mostly present to this day, while COD engine lets you use ALOT of models, grass, trees, prefabs etc. while Source games cant handle the same amount of detail, and objects/models, that's why most of their games are just brush walls, with no proper terrain editing, that's why there's no super detailed terrains in Source games, and no super detailed environments.
Yah I'm kinda seeing the perspective here, Valve and their Source engine seemed to be a one-time thing. It offered a huge advance, but I also have to say it was based off the Quake engine as well, just modified. Let's talk about cars here, that's like taking a single engine, modifying the outerlying parts like exhaust, heads, whatever, and calling it your own engine. That doesn't work.
Call of Duty is more like taking that same engine, not modifying it, but building upon it. That's kind of what I'm seeing here. But with that said, possibly what they were referring to with the new "engine" was the fact that they may have actually modified the source of the actual engine this time, instead of doing rehashes of rehashes. I, personally, can't wait to see the answer to that question. I really hope they did take a good look and maybe modify segments of the code, then the game would be awesome IMO, but this whole "new-engine" deal is kind of out of hand. Not sure who is talking in the video, or who is even developing the title, but it would be great to see someone actually doing work.
