I don't think so, maybe, but it is hardly a harbringer of success. Whether or not it would have happened anyway, we can confidently say bringing 2E to market in the fashion they did was a bad business decision.
2E did not sell as well as anticipated or well enough to keep TSR afloat given the over abundance of 2E product printed.
I understand what you are saying for 3E, but I don't see anyway you can quantify 2E as a business success. 1E to 2E saw the 1E trajectory collapse (which as you noted might have happened anyway), same with 3.5E to 4E.
The bottom line though is I think there is ample evidence to say that edition switch has not consistently been a successful business tactic.
I don't think of essentials as an edition update or change, it was a streamlined version meant to appeal to a different audience. I look at this as fundamentally different than 3.5 or 5.5.
It is closer to the supplements, like essentials, released with 5E
From a business point of view it was certainly more successful than 2E or 4E.
A temporary bump is a bump and a "successful business tactic".
2E sales weren't as bad as internet says at least with core.
Non core bloat sold at a loss did them in. Sold around 2/3rds of 2E similar to 3E overall.
Theoretically it could have made it. TSR was never run well.
80s TSR has two product lines doing gangbusters though comparatively. Until they didn't.
