A date for your diaries! On 23rd July SPACED will finally be released on Region 1 DVD, complete with new commentaries. Whilst in the US, Simon informed Peggster.net on the latest regarding the Region 1 release:

QUOTE (Simon Pegg 23 March 2008)
We recorded a whole bunch of new Spaced commentaries in Santa Monica yesterday.
Edgar, Jess and myself, were joined by guest commentators, Kevin Smith, Diablo Cody,
Quentin Tarantino and Matt Stone. This, together with brand new cover art will hopefully
sweeten the blow for those completists who already have the region 2.
