Hate to be the bearer of bad news, but UK's epic stuff breaks rather easily... at least it does under practical game-play. I saw a 30th-level hero deity one-round a Hecatoncheires using nothing more than SRD and IHB. The man has good ideas, but under-cooked execution (thanks to insisting that he alone do the work rather than share the thunder with a design team; a flaw that will bring his entire effort down around him, as we're already seeing) and terrible consistency (thanks again to his inability to work with others; I mean... when's the last time you paid for a book not knowing that it wasn't even typed or fully thought-out?). All of which leads to a neat-looking set of immortal rules (eventually), but ones that have had little to no playtesting (certainly no documented playtesting) and egregious mechanical loopholes.
Me, I'm looking forward to 4th; I hope it fixes the class-to-class imbalances we saw in 3.x and I plan on only using finished products for any deities for whom I absolutely need stats.
