I found this picture of the new RE262 prototype at In Ear Matters.
Looks like it may be the more conventional style IEM with a bit of a molded extrusion.
Not sure, but does that look like a port on the end of the extrusion ?
Even more so could it be a "screw on port" ie: for different bass tunings? (I'm only speculating here, i wish it was a better quality picture)
