First, it depends on who you think is really making the major decisions at WDW, Burbank or TDO. From a corporate perspective, I doubt TDO has the authority to green light any $100 million plus WDW investment without Burbank's approval. Second, what happens at WDW is largely driven by its financial success. If WDW is making a lot of money for TWDC by building DVCs, raising ticket prices, and cutting corners, then we will continue to get more of that. If, however, revenue and profits are not trending in the direction Burbank wants, "somebody" at a very high level will expect "somebody" at a lower level to "fix it".
WDW has skated by financially for more than 10 years based on reputation (and building more DVCs & higher ticket prices). However, with the wildly successful WWOHP up the road and, more recently, Carsland, it might not be enough anymore. Vacationers actually need a reason to visit WDW, rather than arrogantly taking the position that "we're WDW, everybody loves us". If the rumor mill is to be believed, TDO (or whomever you think is calling the shots) might be forced to take a new approach because the old approach of the last 10+ years is no longer working.
Does this mean the Yeti (for example) will suddenly be fixed? No. However, it does suggest that "the powers that be" are looking for a new business strategy. Perhaps Carsland in DHS and Avatarland in DAK are part of that new strategy. Will both (or even more) come to fruition? It's uncertain at this point. Corporately, change is hard so I strongly suspect there are significant internal battles going on right now within TWDC to set the future direction of WDW. I simply hope it's a different direction than the last 10+ years.
