I'm not sure if this has been discussed or not, but, basically Epic caster levels are pretty much meaningless when it comes to nuking since pretty much all nuking spells are capped at level 20 (or much lower) with very few notable exceptions (disintegrate? and polar ray). So, Sorcs are basically screwed when it comes to casting nukes for high end content as the damage dice aren't keeping up with newer content (no, ED powers are not casting nukes. 1. anyone can use them, 2. they are special abilities and not spells, 3. very long cool downs for the most part). This is a very painful loss of ground when it comes to DPS for high level epics (ever try nuking a group of 10k mobs? not very fun and massively spell point intensive) and I assume it is only going to get worse as level caps increase going forward. Something has to be done...either Max Caster levels have to increase for existing spells or we need new nuking spells.
