As far as I know the old company was liquidated and the assets (the Crusaders) were bought by this new company.
And by the way, in Super League, they have been known as:
Celtic Crusaders
Crusaders RL
The Crusaders
All this is a bit pointless - it's like arguing which is a deeper shade of blue.
If you want to be really picky, they changed names and sports when Warriors went bust. Could say they have something of form for running out of money, regardless of what they're playing and where these days.
That was Leighton Samuel again wasn't it?
