What the leafy feline said.  Plus, when it comes to systems, adventures, supplements, dice, etc., we don't need anything.  It's all wants, not needs.  Not every want is equally satisfied by what is currently available. 

Personally, the last thing I want is yet another adventure that is either bog standard OSR or radically "different just to be different".  the sweet spot in between is an under served market. With good reason given how difficult that balancing act is to pull off when you write an adventure for yourself, let alone communicate it to another person.  Past a certain threshold of quality and precision on the sensibility of the thing, it is effectively impossible for anyone else to do a better job than the GM on the spot.

Use either White Box OD&D, BX D&D, or AD&D 1E mechanics.  Then include a fantastic setting of your own design.  Release it, and call it part of the OSR.  Good illustrations and layout will help a ton.

I approach life in a very digital fashion. On, off; yes, no; is, isn't. I don't care much for ambiguity. That said, I'm open to the possibility there isn't a linear, absolute answer to this question.

My advice is not to target an audience but rather figure out what you want to do creative, write it, and build your audience from there.

If it happens to be something that can work with classic D&D mechanics then you may want to consider a open content clone or adapting the d20 SRD like the clones did. This will allow you to tap into an existing audience for such materials similar to how the Basic Roleplaying family of RPGs operate. Runequest, Call of Cthulu, and Stormbringer all distinct RPGs but share a common mechanics that make it easier to learn the others once you learn one. But it not like GURPS where everything built off of the same core framework. Each version is it's own thing.
