Here's something I remembered reading a long time ago, which I've finally managed to track down, from January 1994:

MEGADRIVE - SEGA
The third entry in SEGA's flagship series ir already in motion. Want an advance? Better make it two. First, the new Sonic will surprise you, not so much for its progression, but for the details in some levels (the bonus one is excellent and we still don't know how could they get the spin-respin-zoom effect), its music and its graphics. Second, it won't be the first Sonic that will be released. There will be Sonic 3 + and Sonic 3 Special Edition. And you'll be able to play with them all together thanks to these cartridges being equipped with a slot on top that will allow you yo stack one game over the other.
Thing is, going by this early info, both Sonic 3+ and Sonic 3 Special Edition were supposed to coexist as the expansion and the complete edition. Two different things.
I was guessing that S3+ would have been the final S&K and S3SE the whole package, but that blurb about the Eternal Champions + is making me think thay perhaps S3+ was the complete expanded game with the Special Edition being the Lock-On expansion...
Also, do we have official confirmation of the whole game ever going by the name "Limited Edition", or were those some developer's personal memories? Because "Special" would make more sense than "Limited", here. EDIT: Found the possible source.
