They don't state it explicity, but they imply it somewhat strongly. First, we have a supra-dimensional being (they say, in Ep.I, something to the extent that U-DO is beyond normal understanding/confines). Second, we have a being contained within the Zohar. In itself, this very strongly implies Wave Existence. Third, U-DO operates via waves (thus the U.R.T.V.s with their counter waveforms). Fourth, we know that, during the Zohar Engine's original activation, it stalled and pulled the WE from a five dimensional universe in order to fulfill its infinite-energy-via-probability-strings operations. Even if this activiation wasn't during the Miltian Conflict (which would be a plausible time for the initial activation; did anybody mention U-DO's existence before the Conflict?), the Zohar Modifier was active by the end of Ep.II (otherwise the Space-Time Anomaly wouldn't have formed), thus the WE should be inside it.Originally Posted by Behold the Void
I could be wrong though; that's just the conclusion I've drawn from the information I've seen so far.
