I just unlocked the bootloader on my shiny new USA GSM Galaxy Nexus from Google Play and...my data was still there when I rebooted. No Android Wizard or anything.
It's as if I did nothing, but I checked MULTIPLE times and I'm unlocked. Got the unlock icon during boot and everything.
same here on mine my data was intact
Just relocked and unlocked again to make sure it wasn't some sort of weird fluke...looks like I'm immune. What's going on here? An unlock is supposed to wipe everything for security reasons.
So all the apps, app data, virtual sdcard files, etc. were all there?
Yessiree. Everything was still there. The phone acted as if nothing happened whatsoever, despite the onscreen warning about losing data.
Same thing happened to me. I was prepared to start all over, but doing the 4-in-1 from the Galaxy Nexus Toolkit, I was surprised to see the only changes were an unlock symbol appearing on the screen at bootup, and Google Wallet griping about my having an insecure phone.
I may re-lock the bootloader now that I've rooted. I'm not sure if I will lose root, but I only rooted to run an adblocker anyway.
For the record I didn't even do that. I simply did "fastboot oem unlock". I like to keep things simple.
Got mine from the play store Friday. Unlock wiped nothing..

Hmmm. You do have a shipping (sorry, "production") bootloader, not an engineering one. Very interesting... Not sure why some devices wipe while others will not, upon unlocking.
There are quite many security issues that could arise from being able to unlock the bootloader without wiping all data, for example, a hacker could get past your screen lock by:
1) Battery pull, then
2) Boot into bootloader using the key combination
3) fastboot oem unlock
4) Flash an unsecure boot.img that has r/w permissions
5) Edit the right files to remove screen lock
But I still have a feeling that this behavior with USA GSM Nexi is intended. Probably because Google intended that phone to be sold only to developers who are likely going to be unlocking bootloaders anyway, and decided to simplify the process?
