it's not an easter egg, but... playing blu-ray on ps3 if you ff at 1.5x the music still plays. it's kind of choppy, but actually a quite enjoyable way of zipping thru the warhorses.
I'm about to buy a US import of SAL DVD as its not available in England until autumn. Is there any indication that the UK release will be different/better or is it worth getting the US one now? I think you can find it for about £9 if you look.
