Here is a pdf of a research paper that surveys new DNA sequencing approaches Several approaches could provide genome (3 billion base pairs) sequencing for $100,000 within 4 years.
Cycle extension methods
454 Corp pyrosequencing
Quake cycle extension
Solexa cycle extension
Solexa corporation’s approaches could reach a cost $9000 to $15000 to sequence a genome.
Genovoxx cycle extension
Polymerase reading methods
Visigen polymerase read
Molecular motors method
Potential $1000 genome sequencing approaches
DLA (Direct Linear Analysis)
DLA enables the real time single molecular scanning of DNA molecules using a nanofluidic device
