Be very wary of 'guardian angels' promising the world.
I can't think of a single "promising the world" statement. Ogren has stated that he wants us in the top league, challenging for cups, euro nights etc. That's a reasonable expectation imho for Dundee United and a reasonable expectation for it's owner, if he wants to build a successful club with his investment.
It's not like he has promised new stadiums, like your current owners, or shelled out on ex big name players like your previous incumbents.
I view Ogren with suspicion, as I would anyone else coming in to the club, but there has been no pie in the sky coming from the club.
You seem to be more ITK than I am though.
