A new round of ELO Japanese Mini-LPs are just released and this tme the complete set of CDs (On The Third Day, Eldorado, Face The Music, A New World Record, Out Of The Blue, Discovery, Time, Secret Messages and Balance Of Power) are housed in a promo glossy, hard-bound slipcase box with Discovery artwork.
From what I can tell, there are no differences with the new pressings of the mini-LP CDs themselves. Some mini-LPs are turning up on eBay with album artwork used as the disc design. Use caution if you order one of these. I've been discouraged from buying anything from the "Russian Federation" because they could be fakes, so I've held back. If you do get one of these Mini-LP CDs with album art on the disc, write me (firstname.lastname@example.org) and tell me whether you believe they're official or not.
Back to the topic, the set with all 9 titles is expensive, roughly $200 or more. But if you haven't tried the Mini-LPs from Japan yet, this might be a good starting point because the Discovery slip box is incredibly well made. If you already own the first edition Mini-LPs, then you're just getting a nice box.
