Why would Google/LG underestimate the demand for the Nexus 4 so much?

I guess there really wasn't a crazy demand for the Galaxy Nexus when it was released. Has that much changed in a year?

The Nexus 4 is the talk of town, and phone connoisseurs are craving it more than an iPhone.

I mean why launch a phone with such little stock ready?

This is certainly generating a lot of buzz for Google but even if they did plan to sell out on purpose... I don't think they intended it on a scale like this.

I'm a die-hard Nexus junkie so obviously this is on my list of must-haves. However, the more time that passes, the closer we get to even newer phones that are even more desirable.
