The UMC has been up and running for a while now, the reason you never hear about it is because he will only accept those who adhere to rules 1 and 2.
But back on track... Sinful's dead on, a re-release of Lethal would be quite pointless and would only lessen the value of existing copies.
As for Collateral, I do have the go-ahead to expose a few details... It's more along the lines of Identity, not as in 'it's gaffed up to high hell' but it's full of effects that could have been released as singular products. Mentalism, sleights, power-tricks... it's all collateral and it will be the last book of it's kind that d+M writes for a longass time (that's why he's packed so much into it)
I did the photography for it a while back but have only had the time to learn one of the effects called Half Triumph, which is OFF THE HOOK
