The Obama inauguration is not my cup of tea; I'm way too realistic for the US nationalistic fanfares. Just as Jonathan Berr I believe the differences Obama can make in his first year (end beyond) are absolutely minimal.
Personally I believe the scenario of a systemic crash is still very plausible. I believe we could be heading for an L-shaped recession with a systemic crash of the financial system before 2015; "peak credit", remember? I'm not the only one believing this scenario is plausible.
The real question you want to ask yourself is: where do you wish to be in such a scenario.
