I think it's more or less because we're getting uncut DVD's anyways.
For me, it's both. 4Kids bastardized the entire show to market it to 7 year olds, and that particular reason is why I hated the lollipop. As CosmicDebris stated, 4kids just went ahead and voluntarily made edits left and right. But if keeping the lollipop ensures that One Piece has a chance to be successful, I'll deal with it since we're getting Uncut DVD's anyway.
does anyone know when these episodes will be realised in the UK? (I'm not talking about the uncut DVDs, I'm talking about the actual TV episodes)
That is a very good question. We will probably get a definitive answer at AnimeCon in their press release, otherwise someone should go to the convention and ask.
