I'm not sure theres much blue sky potential in Relenza. Doesn't the patent run out in 2014? We can already have a fair guess on what the royalties will be up until then.
Another factor is that as Lani moves closer to worldwide production, I expect stockpilers to reduce their orders for Relenza in expectation of sourcing Lani.
I'd love an $18 buck share price as much as anyone mate :D, but I don't see it as realistic unfortunately.
