Creation is a heavily modified Gamebyro. Sure they did work on it but Gamebyro was there pallet and they didn't make it much better.
Did I ever blame Gamebyro in my post? Read it carefully, all I stated was they took time to make the Creation Engine so F4 may take two years instead of Skyrim's three.
And Bethesda pushed the limits of the same version of Gamebyro that was used back in 2006, that's why NV was so laggy and buggy.
I didn't regard you as directly blaming Gamebryo but the sentiments you and the vast majority of others around here possess. Also that comment wasn't keeping in mind how BGS might develop their next game. I didn't refer or even think about that when replying to you at all and rather people's aggravation being directed always at the wrong target or at least not taking the entire situation to mind.
Again Creation did use the same base as Gamebryo, any eye can see that. And I wouldn't be surprised if Gamebryo assets were converted rather than full scratch. Think possibly iterations of Windows. That doesn't instantly mean it is Gamebryo as it license-wise can't be for all the reasons I stated above. Otherwise they'd very clearly be getting sued right now. Using a foundation from it also doesn't make it a heavily modified faux Gamebryo. Let's not forget the bases a large amount of engines use. Or even if we go to OSes Windows to Mac OS also have tech bases borrowed from somewhere. That doesn't make the product that nor make those two respective OSes one or the other.
Not to mention Bethesda didn't develop New Vegas but did hand their own modified variant of base Gamebryo to Obsidian. Obsidian by any means didn't particularly fully push Gamebryo with their additions. All in all it ended up worse than what they started with because first off Obsidian isn't exactly home to the best programmers on the planet. Second off it was an engine they weren't familiar with and BGS wasn't able to help much either, even when considering the small development time frame and small team size. Josh Sawyer said as much himself:

I wouldn't say it was small, but by comparison to something like the Assassin's Creed 2 team, I guess it was. A lot of people worked on it at various times, but I think our team size at peak was in the low 50s. When we started working on F:NV, no one on the team had worked with the engine before.You probably know that but that's to keep in mind the tech mindframe and that even from "vanilla" Gamebryo it diverges as BGS itself modified it then a less masterful Obsidian further modified it, although with small and not efficient touches. However I don't know Gamebryo to know well enough what version they modified it from and/or if the latest version or earlier version was being built from it.
The entire thing is to point out Gamebryo while by now stale has been an admiral enough engine and that the Creation Engine itself diverges enough to not be considered just a more pushed version of BGS's modified G-base. And if it did shortfall your expectations(On the AI front it highly did for me) take it less on the base they took from the previous tech they put into Gamebryo to make this new engine, Gamebryo itself, or Creation Engine as it is now. CE as is is fairly competitive with current industry standards. BGS didn't put the man power and resources to "pimp it" to a high extent or doesn't have the available skilled persons to. Or even current gen consoles could be a root cause.
As for the timeframe of the next game. I do expect the 2 1/2 - 3 1/2 years as the 1 1/2 - 2 years didn't cut it for New Vegas even if BGS is bigger and better funded and Creation Engine is set to not need a new built engine for years to come and be more modified, adapted/optimized to new hardware, and added to as time goes on.
Plus even BGS is ambitious enough to want to craft a memorable game especially with the bar New Vegas upped and renewed 80s/90s crowd interest in these games along with possibly an internal need to not be outclassed by the Wasteland Kickstarter with words making round linking it to Fallout. And we all know about 95% of game players/ Fallout fans, the majority of them 3/NV fans, have no idea what Wasteland is let alone Interplay Prod/Black Isle.
They'll probably aim to be a launch title, especially to Microsoft's next console.
