hey here is a fun fact. You are making assumptions and acting like you know for certain that there wont be a LTE version when in reality you don't have a clue. Watch this video
Motorola. On Display. - YouTube (around the 30-32 min mark). "at google we believe faster is better" . "at google, we have leared milliseconds matter when making a search". We have top google executives singing the praises of 4G LTE and talking about how much more useful it is than 3G. Do you really think they would release a flagship google phone without it? If not you may want to reconsider.
Also, the nexus may be used by developers as a reference device but it is not purely a developer phone. As soon as it was offered to the general public and advertised the same as any other retail phone that argument went right out of the window. My roommate is an android developer and he receives phones for free to develop on. I would also say that all google employees and most developers use G nex's and don't you think these people would be the most fanatical and sensitive to a device that has poor specs? Google will release an unlocked GSM/HSPA+ version of the LG nexus and sell it via the google play store with 99.9999% certainty. However, I would be VERY surprised if they did not released a 4G model at least at a later date.
And yes I know there are other high end devices but all of the run crappy skins of android. since I use my phone for work I cannot root or rom my device or i loose access to company emails. I want a nexus and I want it to be high end. If you cannot afford to pay $300 w/ a two year contract for something that you use every day / all day to have the best performance possible maybe you should have studied a little harder in school because that is not that much money. I never said releasing a cheaper model was bad but they should give consumers the OPTION between that and a higher end device. Read the comments on any article about the LG nexus and you will see that this is what the hardcore users want .
