Nah, the idiocity was having two upgrades planned even before that, and neither were sufficient enough to keep Amiga competitive. Even if those guys stayed it would only help with their reputation and that's all.
As much as people love it the 1200 was nothing. It came out in 1992, you could barely play Alone in the Dark or fast Wolf on it
Not even the other marginal upgrades could run doom even without full screen, ANY OF THEM, even the Mega ST could play doom, Falcon could play Ultimate Doom and someone got it to play a compromised but impressive port of Magic Carpet.
None of those last Amigas could play any popular games 2D or 3D, until their bankruptcy in 1994.
Even office programs were lagging, crashing, or received little if any substantial updates from 1988.
In 1993 it was even falling quickly behind in video and graphic design, it's main forte.
In comparison, Maxed ST and Falcon were still good for audio programs, and you could make games on it and port them upward onto Windows PC easily.
