I bet you could buy a blu-ray player for £48.99!! Then you wouldn't need the DVD version!!!
He could, but it wouldn't be very good. You need to spend, in my view, about double-that, to get a decent one, that's going to give you decent picture and sound-options, allow for easy and reliable firmware upgrades, and not throw a hissy-fit with the Star Wars Blu-Ray discs.
A lot of people still want SW on DVD, not Blu-Ray, and are desperate to get the original, untainted trilogy (the double-disc sets that came with the remastered versions of the films on disc 1, and the 4:3 letterbox original editions on disc 2) for a reasonable price. Even though Blu-Ray may be visibly and sonically superior, there's a high demand for the original trilogy, even on the slightly inferior DVD format.
Lucas could make a small fortune all over again, if he put the original, untainted trilogy on three Blu-Ray discs, with a handful of extras. Sadly, we know he won't, but that's what the public want. Not the messy, botched-to-hell remastered editions, with new CGI retouches all over the place.
