For sealed armatures the housing doesn't really matter, only the length and diameter of the sound tube leading into the ear. If the nozzle - and the acoustic filter in it - are the same, they very likely sound the same.
However, I read the SM3v2 have 24 Ohm impedance, while the SM3v1 have 17 Ohm impedance. With multi-armature IEMs with crossovers, one Ohm more or less can make quite some difference (much more than with dynamic drivers) - so I guess they redesigned the crossover or used slightly different tuned armatures. Franck Lopez from EarSonics however states they sound the same.
Needless to say, I am really curious about those new ones, with the SM3v1 being my favorite IEMs, and all.
