For the near future, CDs but prices in the UK will have to come in line with US prices. Longterm? some form of download format which gives a decent quality for playinf on something other than a MP3 player ie lossless compression as per APE or FLAK. The key issue will still be quality. How many 70 minute CDs have you bought which shorn of 5 "filler" tracks would have been a good 45 minute LP? This is what is hitting the pop market as with downloads you don't have to buy the dross.

Oh and BTW Tyke, content needs to be made available in any format, be a good troll and pass it on :)
