None of the next era books are really exciting me so unless these characters are in X-Factor, I would prefer a book of the unclaimed X-characters: Madelyne Pryor (Goblin Queen), Alex Summers (Havok), Lucas Bishop (Bishop), Roberto DeCosta (Sunspot), Lorna Dane (Polaris), Warren Worthington(Archangel), maybe Allison Blair (Dazzler) or Clarice Furguson (Blink), and even Nathan Summers (Cable) more than anything announced so far.
Or maybe this group can be the foils against the Uncanny X-men team. friendly rivals like Alpha Flight used to be to the Uncanny X-Men.
