DO I have to install every update before installing iOS7?

I was getting ready to install iOS 7 on my iPod touch to check it out before I do the same for my other devices, so I backed it up to iTunes on my PC, and then noticed this:

iOS 6.0.1

A newer version of the iPod software is available (version 6.1.3). To update your iPod with the latest software, click Update.

So do I really have to serially update iOS through all of the updates since iOS 6.0.1 first before updating to iOS 7????? If so, this is gonna take awhile...

it is the newest one so I would imagine it is! I cannot see the update for iOS 7 on the OTA option either. I just keep seeing that 6.1.3 one.

But the other poster that said it's not available because the server crashed may be on the right track. I'll try again in the morning or later this weekend!
