Te hablo / hablamos más tarde / luego
This is not a question.
In colloquial Spanish, you often use Present tense with a future implication; Future form is less usual, particularly in Latin American Spanish, because it is more formal.
But, if this is kind of threatening, like when you tell to a kid "I'll talk to you later", because they've done something wrong and you want to talk to them in private about it, the usual would be "ya hablaremos más tarde".
Hope this helps, regards.
