Looks like MtGox has given up the partner track, and is becoming its own bank (more or less). This information came up in a discussion in French in #mtgox very recently:
20:19 <@MagicalTux> nous sommes en train de nous enregistrer en Europe comme
entité financière, ce qui devrais nous permettre de gérer
un plus gros volume sans causer de délais
My knowledge of French is very limited, and I hope a native speaker can translate. I have had some help from Google Translate and my wife, and think it means they are registering as a financial entity in Europe (EU), which enables them to handle a large volume of transactions without causing delays.
Regarding partnership with existing banks and payment services, the response was:
20:24 <@MagicalTux> nos avocats nous ont déconseillé la même méthode pour
différentes raisons dont je ne peux pas parler
20:27 <@MagicalTux> plus exactement, nous avons conclus qu'il nous faut une
license directement
20:28 <@MagicalTux> (les raisons pour lesquelles bosser avec un partenaire ne
rend pas l'activité plus légale sont compliquées)
My understanding: MtGox's attorneys have advised against this for reasons which he can't talk about. MtGox has concluded it needs a direct license. Partnering with a bank doesn't make the activity more legal, and the reasons for this are complicated.
More about becoming their own bank:
20:33 <@MagicalTux> cyrflo: comme dit plus haut, nous sommes en train de créer
une entité financière en Europe
20:34 <@MagicalTux> (il faut compter 6 mois à 1 an pour que ça soit fait)
20:35 <@MagicalTux> Je ne peux pas donner plus de détails pour l'instant pour
différentes raisons
20:35 <@MagicalTux> cyrflo: c'est cher aussi, jusqu'à cette année nous n'avions
pas les moyens
My understanding: MtGox is creating its own financial entity in Europe. It will take 6 months to a year to do it. He can't give more details at the moment for various reasons. It is expensive as well. They couldn't afford it until this year. (This means MtGox is liquid as well, for those still in doubt.)
He didn't say how long he has been on this track. I don't know if he means 6 months to a year from now or from sometime earlier this year.
