Open design platform. Yes eventually.
UGC has never failed. It's success is massive on PC side, the reason why it succeeds on the PC side is because of it's open environment. If a UGC game comes out say Half Life 1 & 2. It is assumed that Valve doesn't have to do the entire support load. What I mean by support load is community collective sites that allow people to share. An example would be
http://www.l4dmaps.com/
http://www.moddb.com/games/half-life/mods
http://wow.curse.com/downloads/wow-addons/default.aspx (UGC UI for WoW)
http://www.fr2db.fr/ (freerider tracks for a smaller game, small developer too)
I could go on for a long time showing UGC. Just having a UGC editor doesn't mean success. It's all about supporting the community of UGC. Something that as the OP has mentioned that the dictorial nature of console does not nurture such an environment.
Console will eventfully be open platform design, or more specifically console makers will include a sandbox environment to allow outside development while keeping licensed material safe.
Squilliam: On Vgcharts its a commonly accepted practice to twist the bounds of plausibility in order to support your argument or agenda so I think its pretty cool that this gives me the precedent to say whatever I damn well please.
