Nah, I don't really think so. But reader Mr. Skellington wrote in with a good point about the classic trilogy, in light of developments in ROTS:

the one thing I haven't seen anywhere is why does Obi Wan say "That boy is our last hope" as he leaves Dagobah in Empire? Yoda quickly offers up what Obi Wan should know "No, there is another."

Did Obi Wan soak up too much sun in the Jutland Wastes? Wouldn't he know and expect that Leia would be strong in the force as well?

I've never given this much thought, though in truth it's been a continuity issue since 1983.

In Obi-Wan's defense, he and Yoda have been training Luke for a long time now, so from the "investment of resources" standpoint, he's clearly the horse they're betting on. If Obi-Wan also senses that time is running out (e.g. if the Emperor completes the second Death Star), he might have a legitimate case to say, "That boy is our last hope" in light of the ticking clock.

Yoda is really the one who's being overly optimistic here, suggesting Leia as an alternate. Not that Leia can't handle the training, but Yoda's gonna die! Some coach he'll be!
