Gone for good. But I'll go a step further and suggest that they never were actually as great as people suspected, and were overrated the entire time. Don't get me wrong, they have fun games and stuff I enjoy but they basically built their entire studio off of just copying Dungeons and Dragons into the digital realm with poor graphics, poor animation, and above average writing for gaming at the time (which had extremely primitive writing mostly). They never excelled in game design, graphics, or animation.
They had a good run being one of the only devs in early game history with decent writing and sidequests. They peaked when they first transitioned to consoles, and had a real golden era for a short period when they felt inspired (KOTOR, Jade Empire, Dragon Age, Mass Effect).
Even then, they basically made the same game over and over again.
Overrated for sure, and the staff their for their best run are long gone.
