As a side note, I think that speculation about captures, releases and evolutions is pointless until there are definite hints about such an event occurring. Take the title of DP122 as an example - Evolution! This Time for Pochama? With that, yes, you can debate it, but to be honest it was always going to swing towards Pochama not evolving; the question mark in the title, along with Pochama being featured in the poster for To the Conquering of Spacetime. Debating something like when/if Buizel will evolve, or if he'll be released, is pointless, as no hints have ever been given as to any of those things. =/
I enjoyed the two episodes on the whole, even though one was essentially a filler episode. The Yukikaburi in 121 was rather amusing, but I don't see why people wanted for Satoshi/Takeshi to catch him. >>; 122 was a character development-heavy episode, focusing on Pochama, who has become a lot more bearable in recent times. At least it gives an end to any speculation about Pochama evolving, I guess.
