New Champion?

Im usually not one to beg for new champs but I could not help to ask this question:

When is there going to be a new champ coming out this year? It's now almost April in this year and we have only received a Galio rework?

Please advise Riot. I would love to see more champs on the Rift sooner than later, and I feel there has been a decline in the amount of people playing league. Thanks for your time.
