I can understand your opinion. Lego stands for innovation and creativity. But I think it is a chance to see if there is a strong base in the community to bring back some classic (and in my opinion some really nice) sets of the past. We're not living in the past only because we love some "Oldies". You won't lose anything to test it. And LEGO is only interested in selling sets and making money.
And in my opinion CUUSOO offers some other options. For example bringing some additions for existing sets like an additional wagon for the Emerald Night or the Maersk Train.
