It was coming, yeah. Question now is which is coming first; CLANNAD or Haruhi? Though CLANNAD got the first announcement (with a 30-second preview), and also has the previewing at the TBS Anime Fest coming next month, which shows greater preparation for that at the moment.
Official announcement to come onto the website on July 7 (Tanabata).
