yes they are both 25 man instances.
40 man raid instances can only be found in "WoW-Classic".
I read some blue post that they do not plan to go back to
40 man instances, and i am quiet happy with that.

Kaplan believes that having Naxxramas as a new 10- and 25-man introductory raid serves a few functions for Wrath of the Lich King. First, it lets the vast bulk of players experience what many believe are some of the best raid encounters Blizzard ever produced. Finally, it serves as the start of the new "two-tier" raiding system. Going forward, all raid dungeons will have both 10- and 25-man versions with their separate itemization lists and progression tracks. There will be no attunement requirements nor will getting into a 25-man raid be dependent on any 10-man raiding.
Usually Guilds which are considdered "end game" will not farm World
Bosses anymore, only on rare occasions and probably only to equip twinks.
Guilds who just made it it recently through the Black Temple should actually not have alot of hope to come by Brutallus in Sunwellplateau, because he is a pretty
hard gear-check for the entire raid. (Correct me if i am wrong)
