My wish is that governments worldwide can temper the egoistic, a-social, uncontrolled behavior of the corporate 'powers that be'.
We vote democratically for our politic leaders, but the people who really run the world are invisible, but have the power to mess it up for lots and lots of people. I hope that in 2010 more power will be brought back to the people (and governments).
And of course good health to all good people (don't care about the bad ones

)
Elvis wish for 2010: that Sony (BMG/RCA/MGM) will finally treat Elvis the way the Icon of Music should be treated: less budget releases, and more innovative, contemporary releases. More focus on the post-1968 period. Going for quality, not direct sales persé.
I hope that 2010 will be the year that we see Elvis movies being released in High Definition and that Elvis On Tour being released in a DeLuxe version (separate shows and the special).
