Rare posted a new update on their news page regarding some downloadable content soon to hit Nuts & Bolts: L.O.G.'s Lost Challenges. Apart from the obvious additions of new challenges, which can be inferred from the title, it is unknown if it will also include a new game world, but it does also seem to hint that also included will be an expansion of Klungo's wonderfully egotistical arcade game, Hero Klungo Sssavesss Teh World.

This update may also be related to the vehicle contest Rare was holding; perhaps the top vehicles will be chosen as a L.O.G.'s Choice vehicle for a new challenge?

According to the update we can expect to find out "as soon as next week".

UPDATE: The newspost has been updated to say that we'll find out more information " soon (following a minor technical delay caused by Grunty's gremlins dropping a spanner into the works)". When this is remains to be seen, although Brother Mike stated at the official Banjo-Kazooie forums that (as far as he knows), this will not affect when the DLC will release, which should be "in the near future".[1]
