The PowerShell Summit took place in North America in April and many of the prominent PowerShell people were there. And from what I read there were a lot of great presentations.
The PowerShell Summit 2013 North America conference schedule can be found here. Thanks to Don Jones and PowerShell.org (most of) these sessions are available for download: http://powershell.org/wp/2013/04/22/summit-downloads/
Videos are available here:
So even if you weren’t able to attend, you can still learn from their presentations. Or if you did attend, you can review them again.
