I think the main difference is that even people who are positive about this change of ownership, recognise the fact that things could quite easily go tits up.
Other than my tongue in cheek reference to European football, I haven't noticed anybody jumping about for joy and forecasting endless riches for the club, both in terms of money or on field success.
Experience has told us that these situations, where foreign ownership is involved*, can often result in disaster. Therefore, although there's a sense of relief that change is afoot and that we might survive relegation and thrive in the SPL (or whatever its called), this is tempered by the fact that there's a lot of uncertainty.
As Div says, let's wait and see what the new owner's opening gambit is before we start weeping and wailing.
*Just in case people think that I've developed a case of rampant Xenophobia, UK based consortiums, sometimes involving fan ownership, are equally capable of making an arse of clubs too.
