Agree, I think with everything going on there seems like some vague possibility for Disneyland itself to move forward towards that Esplanade in the next 10 years. There's just so much resort flow benefit that could be achieved by having a way for Fantasmic to dump out an alternative exit of the park that isn't marching down Mainstreet.
Now DCA on the other hand... with DCA seemingly going in on Pandora (+ fingers crossed Avengers), odds of it both expanding across Disneyland Drive to begin with AND expanding in such a way that it entirely necessitates an entrance wrapping around the whatever Paradise-Pixar hotel is called all the way up to Down town Disney seems incredibly unlikely before it's worth even talking about. That's so far in the future. It's possible even if it does go across the road you'd still have to double back into the main park for many, many, many years.
Just measuring an extremely optimistic pathway, to get from Paradise Pier to Downtown Disney it's at least 50% further than from Winnie the Pooh to Downtown Disney in their proposed plots. Disneyland makes sense to immediately build towards that area and DCA does not.
Essentially the very last thing I imagine DCA getting is its entrance in the esplanade. Long after much of pretty much all the plots of land are utilized. Aka never.
