I don't think they tour. Maybe some TV appearances in the USA and some magazine interviews worldwide but that's it. You can't compare the boxset to a best-of-album. It's something totally different, just when you look at the price. 59,99 Pounds (that's what HMV London said it will cost) isn't something that the masses would pay for something. A box set is for the fans and isn't made in such a high Number.
