Gosh I still have some hope, even if that has slighty fade away. I want concrete stuff, not just words, but I'm beginning to think my prayer won't be heard for quite a long time. They are all busy. Prove me wrong girls, please! 
I agree with nabojsa, what's the point of staying a band if not releasing music ?
To keep their brand alive
To keep the opition of a backup should there solo careers fail
To not upset the fans
In their own heads they've split/on a break but i think they do want to come back but dont know when!

there's nothing to gain from splitting officially unless they all hate each other which we know is not true.
It makes sense, what happenned when Steps, S Club etc split and said they did
The fans left them and found other groups and the media stopped caring about the least famous members.
It makes sense - it keeps 'the brand alive' and it works all five still grace mag covers and news headlines not the case when similar bands split officially.
