the new 52's continuity is mostly similar to the old continuity just with vertigo and wildstorm added to it. but all of the shit that happened before like death of superman and all of that its all still part of the new 52 continuity dc has flat out stated that just a few slight differences like instead of it all happening in like 10 or so years its been shrunk down to 5 years and the characters are all younger and superman and lois arent married (yet). just small shit like that is different but the pre flashpoint continuity is still the same as the new 52 continuity so we should all stop worrying and no there is no point in them going back becuase its all basically the same.
