Yeah, ok!
What crisis? I feel like most everyone realized that it is likely just flashbacks, save a few who initially misunderstood the context of the episode. The excitement stems out of seeing Misty and Brock again, even if it is "old material."
Over here things were settled, but you should see those twitter and tumblr accounts or even devianart art accounts where people are throwing celebrations because they think Misty and Brock are joining Ash's group.
The same thing happened back in 2007 when the Misty lure appeared in Buizel's capture episode. Kasumi's VA made a comment and people sat there for all 4 years of DP expecting to see Misty but she never actually showed up.
