Well, we're pretty sure it is there. The alternative, that gravity is actually variable, is extremely remote, especially after modelling based on data from the WMAP satellite give an accurate simulation of the universes' life.
But yes, Dark Matter/Dark Energy is a big 'X'. It could very well be a blanket term for a whole new range of matter and energy that will be incredibly varied. It's a little like knowing that matter and energy exists without knowing about knowing about atoms and forms.
A future periodic table of Dark Matter? Sure it's quite possible. Heck, I'd even be prepared to posit likely.
