How about having having two folders, dense and sparse, in the matrices folder. The dense folder contains densematrix.py and linalg.py. densematrix.py contains the class DenseMatrix (the current Matrix class, or should the name remain the same ? ). The sparse folder has dokmatrix.py, linalg.py. dokmatrix.py contains the class DOKMatrix (currently SMatrix). More sparse reprsentations would be added here later. linalg.py contains routines for factorization, solves for dense and sparse respectively. This is much like what scipy has. If we choose to remain the current Matrix class to DenseMatrix, we can have a file matrix.py in sympy/matrices/ which has a Matrix class which serves as a wrapper over DenseMatrix, and the various SparseMatrices.
As to the class hierarchy, I intend to keep sparse and dense separate. There are only some printing and other utility functions that they could share. So, some more abstract claasses like _printable_matrix, would also be there.
