I know most of us have seen the letter already, but just in case, I will recap by saying this: Adam is very sorry for the delays that have kept him from releasing his new music. He never really clarifies what these delays actually are, but he just describes them as "situations out of my control".
But what we can safely assume from this is that the new album will probably NOT be released March 31 as predicted by NewReleaseTuesday - but it's still possible that we can expect something, like maybe a new single. This is just my speculation - it's only a guess.
But whatever will happen, we are assured of one thing: Adam has not forgotten about us, and we can expect great things coming up soon.
Always keeping you posted,
