Oisín Grehan has a good list of the new cmdlets in PowerShell 2 (currently in CTP3 and the Windows 7 beta):

It's cool having a list of all 106 new cmdlets, including such useful ones as:

• Test-Connection (ping)
• ConvertFrom/To-CSV
• Start/Stop/etc Jobs in the background
• Get-Random (useful for drawing prize winners at user groups!)
• ConvertTo-Xml

PowerShell 2 has a bunch of cool new features, and feels like it's getting real close now :)
