I think now that it is open and projects can help craft Launchpad, rather than multiple instances we will see more projects move to Launchpad and add to the existing infrastructure now that they can trust that they have a degree of control over where it is going and which features will be implemented.
Hosting is largely not an issue for most projects, openness is.
Just like there aren't many Sourceforge clones out there (I think GNU has one called Savanna but that's about it). Once the platform is open and trustworthy there is very little reason to merely do hosting yourself rather than engage with the existing service and develop it.
This all hinges on the fact that now that the code is open the community will be as well naturally. E.g. it would be hard to imagine say Fedora going to Launchpad.net for it's needs if they felt they were being asked to hand out all control to Canonical rather than an open community they could be part of. If that level of openness doesn't happen then we will likely see either spawning of distribution or project specific Launchpad instances or a complete discarding of LP as a future platform choice for these projects, of which I think the latter is more likely.
