Speaking on Jonathan Ross Show, the group said that they feel comfortable now as a three-piece reported Digital Spy.
Gary Barlow said: "It's different definitely but at this point we've kind of been working as a three now for over a year so we've really got used to it and I must say the support - as you've heard - has been unbelievable, it's lovely to be back and we can't wait to play live."
Of a possible split, Howard Donald added: "That was one of the things, when we were a three and Jason left, we didn't really know whether the fans or the supporters would like us to come back and do another album but from all the support we thought, 'Well we love doing music, let's give the fans what they want as well!'"
All agreed that the door remains open for both Orange and Robbie Williams's return, with Mark Owen revealing: "We hope one day they both come back, it just wasn't the right time for them so you never know."
Williams has already stated he is "pretty sure" he will rejoin the band, with Barlow adding last month Take That are "five people".
