to those so calm about the Western side of Nintendo thing: I envy you. Let's see if you'll still be of the same opinion if we'll have to wait for a Direct with some relevant new announcement or localization for months...
Sorry, but... Nintendo kept doing what they have always been doing since the launch of Nintendo Direct: some Japanese-oriented Direct, some Western-oriented Direct, some Direct about specific games.
The last worldwide Nintendo Direct was less than a month ago, and was focused on
Hyrule Warriors (they announced new characters and the Limited Edition).
Just a few months ago there was an event (i.e. E3) which brought plenty of good news about Wii U e 3DS software. Gamescom was also a big event; no announcement but a lot of new games (
Super Smash Bros. stand was one of the busiest) and demo (good coverage by many big websites).
Many recent announcements about Europe came outside Nintendo Direct, while being typical Direct news:
Mario Kart 8 DLC blowout;
Super Smash Bros. for 3DS Limited Edition;
Pokémon Omega Ruby / Alpha Sapphyr Limited Edition;
sales promotion linked to Super Smash Bros. new and
veteran challengers;
reveal of Fire Emblem: Awakening characters in Super Smash Bros.;
Sonic Boom release date. why did they choose to spread this news through social networks, PRs and the official website? Probably this might be due to Iwata's health conditions, and the decision to keep a low public profile. But
there were a lot of news nonetheless focused on Western markets.
As far as I remember,
Nintendo never announced release dates and other launch information about first party games a lot ahead of time, in particular for those which are not internally developed.
Monster Hunter 3 Ultimate European release date and bundle was announced in January and in February, when the game was coming out in March. Also, Nintendo is focusing on one big game at a time;
Hyrule Warriors is a priority right now, then
Bayonetta 2 in October and so on.
The only two events heavily focused towards Japanese audience were
Fatal Frame's and
Pokkén Tournament's. But the reason is simple: the first one is marketed by Koei Tecmo (and the latest Wii entries have always been announced to Japan first), along with the movie and the manga; of course, the last two will probably not come out in the West, while the game might be.
Pokkén is, instead, an arcade game for now, but the official Pokémon channel uploaded the trailer anyway. This is how marketing and promotion works, and have always worked.
As for
Senran Kagura 2: Deep Crimson;
Final Fantasy Explorers; and the other games you mentioned, software houses never stopped to make Japan-oriented events. Furthermore,
Final Fantasy Explorers has already been trademarked in Europe and North America so it is likely coming.
The last thing about Nintendo localization of Japanese third party games; in the last year, Nintendo brought in Europe:
Bravely Default,
Professor Layton and the Aslant Legacy,
Professor Layton vs. Phoenix Wright,
Inazuma Eleven 3 Team Ogre Attacks!,
Inazuma Eleven GO, and they are going to bring in the few next months:
Disney Magical Castle,
Fantasy Life and
Monster Hunter 4 Ultimate.
I don't think one can complain about their efforts in brining third party games in the West; one might question about which games they are localizing, but the effort is surely there.
