I am pretty certain that Ninjak will be getting his own book, but they will probably wait for when its best to have him break off of the X-O series... since their goals are currently aligned, when their paths separate I predict a page at the end of that issue stating "FOLLOW NINJAK IN HIS OWN SERIES!". And I will... because he is awesome.
I, too, have been struggling for cash lately. Something of particular note with these series are that each of their initial trade books will only cost $10. Since the release of the trades is pretty well staggered you should be able to pick up any you are wanting without too much difficulty.
