No, not really. I didn't see this at all.
Well a month or two back, the Bukkit team got hired to be part of Mojang. They had meetings to discuss how to do the Mod API, and it will be similar to Bukkit although you'll need a converter for your plugins. More so, Dinnerbone of Bukkit has been doing TONS of bug fixes to the game since he become part of Mojang.
