Reply to Apple's Logic Pro X

It has been announced!

Just now that I was going to attempt learn music production in my Logic Pro 9, now it has a new version for $199

Should I buy the new version and start learning on the newest software or should I stick with Logic Pro 9 while I'm learning and then when I master it, upgrade to Logic Pro X ?
