I think the news is poor. Debt 'relief' is one thing but it is another to forgive debt unless the circumstances change greatly (complete change of regime/institution of democraticish reforms) otherwise you're just asking for more debt, more poverty, more dictatorship, more hardship all around.
The best you'll get is a promise of a controlling or influencial vote in future economic matters, which won't mean squat in terms of real upward economic change.
From a conspiracy POV, that may be what the G8 is really after.
