Everyone and there dogmeat is saying the same thing about Bethesda holding back because of TESO which admittedly seems likely but people forget that TESO has a staggered release as the pc version comes out on the 4th of April while the next gen versions are about a month or two later so we've go a while to wait to see if this hypothesis bores any fruit.
But it's also dangerous to pin to many hopes on this hypothesis as it could quite easily just be coincidence and Bethesda may hold of for far longer than the TESO release.
Basically get excited for nothing until Bethesda says so
Edit:
The backfires of skimming through threads...looks like i've got the wrong end of the stick, Todd Howard has said many times that BGS don't make multiplayer games it's hard to see him going back on that.
