Yes, the majority of the coins that were announced last year have been followed through on. However, not all of the coins have been released yet. For example, Tezos has yet to be released and is still in development. Additionally, some of the coins that were announced have been delayed or have yet to be released, such as Zcash, which has been delayed due to technical issues. Overall, most of the coins that were announced last year have been released, but not all of them.
