What Might Knock Illumina Off Its Perch?

The big sequencing platform news this week is Roche's announcement that they are ending their collaborations aimed at developing new sequencing technologies.  A collaboration with DNA Electronics aimed to create an Ion Torrent-like system whereas a more ambitious effort with IBM aimed to create instruments based on "DNA transistors".  As noted by Forbes' Matthew Herper in a thought-provoking piece, Illumina is sitting very high atop the sequencer market.

For What is a 454 Still Great?

I've been mulling this item ever since AGBT, but have struggled with the title.  I don't want to sound like I have a grudge against 454 ( truth is I just got some good datasets off this technology), but I do believe that they are few papers away from being stampeded.  Or perhaps not; perhaps the community is really wedded to this platform.
