The thing is that you can just drop new rides (like Tower of Terror or Ratatouille) but they don't necessarily fit in... Or you can rethink what was wrong in the first place and make tougher and more expensive decisions. The new management has been much more receptive to money spending for quality product and returning to the story telling route. If all people want are rides, they might as well go to La Foire du Trone. Doesn't matter if you put a 150 million euros ride in there, if it's just dropped there, it still looks like a fair with a bunch of rides. High end rides but not a Disney park.
So they tried to make it look better (like DCA) but it is still a somewhat jumbled mess. And Disney Studio Paris has the same problem as California Adventure did: it is very easy for people to walk a very short distance and compare to the fantastic (albeit, aging due to maintenance issues) Disneyland Paris (or EuroDisney

) next door. And when you just do some place-making improvement, the overall glue doesn't stick because the story is still not there or well realized.
However, one of DLRP most maligned asset is slowly turning into one of its biggest resource: the very very large quantity of Hotel rooms available in the resort IS bringing money and has been one of the highest increase in spending in all resorts, worldwide. Gas prices have been escalating and DLRP has both easy road, but also train and even plane (si on considere les acces RER depuis Roissy, ainsi que le TGV parfois... quand ya pas de greves SNCF... bref, passons

...). Of course, a lot of people would rather stay in Paris and commute but if you offer more compelling reason to 'stay in the magic' (again, with a more immersive story telling, a better sense of place), people would rather stay in 'Xanadu or Pandora (if you liked Avatar

)' than go back to some realities.
Plans have been drawn, blueprints are all there, management is torn and timing may or may not be right... There's a lot of investment already taking place in parallel and the parks investments are some of the longest ones in terms of ROI, they also don't want to spread themselves too thin...
Bottom line: wait and see for a little while longer. DLP will be 20 next year, WDSP will be 10. Too late to do anything NOW but good timing for some announcements.
