Under the new syllabus,
There will still be 3 sections, mainly
-言語知識(文字・語彙) Knowledge of Language (Vocabulary)
-言語知識(文法・読解) Knowledge of Language (Grammar/Comprehension)
-聴解 Listening

The guidebook is all in Japanese, i will post more info, once i have finished reading the guide book.
Updates:
In the new exam, there will be a base mark (基準点). If one of the sections is not above the base mark, you will fail the whole exam, regardless of how high your total score is.
E.g
-言語知識(文字・語彙) : Marks: 50/60 Base Mark: 40/60 PASS
-言語知識(文法・読解) : Marks: 50/60 Base Mark: 40/60 PASS
-聴解 : Marks: 30/60 Base Mark: 40/60 FAIL
In this case you will fail the exam. This is damn bad news for those people who cannot pass listening.
At least it can be a gauge for employers who employ staff who have the new certificate. That at least your Japanese is really of a certain standard.
