Nintendo may have brought forward its final Wii revelations somewhat, as the firm's European arm pledges a major showing at the upcoming 2006 Games Convention in Leipzig, Germany.

A one hour presentation, tantalisingly titled "Wii Prove Our Promise" will kick off at 10.15AM on August 23rd at the well-established German show that so easily usurped the British summer gaming calendar.

SPOnG remembers that European press were promised something big from Nintendo at the Leipzig event last year, only to be sorely let down. A presentation called "Expand the Definition of Gaming" left attendees baffled as to what they should have been seeing in a run of dated press clips from various Nintendo footage already in the public domain.

Nintendo has pledged major, final announcements for the Wii at some point in September and although the Tokyo Game Show does look set to be the venue where the firm will finally outline exactly what we can expect, there is some belief that a split announcement will be made between Europe and Japan.

We are still to learn official pricing, release dates, shipping numbers, launch titles for any region so there's still plenty of big announcements to come.

We'll be sure to update you from the German even after the showing.

UPDATE: Nintendo France has dropped hints that as many as five brand new Wii games will be shown during the event. We'll bring you clarification of this as soon as we can.
