I like saying PSV, and I feel as long as we keep that other name out of the conversation in general, it will go away.
Unfortunately, at this time, they haven't talked much about the purpose or cost behind the 3G. You'd love to hear something like "it is freeeeeeeeeeeeeeeeeeeeeee", but that is very unlikely. These aren't eBook readers, so these services might have a silly fee like $30 a month, which is a relatively standard data rate. Here's hoping it isn't at all that high.
Unfortunately, with the exception of Battlefield 3, I didn't get to see anything that I wanted to. That includes the PSV. When we were going to see it, there was a scheduling conflict of typical E3 proportions, so I had to cover the other stuff. It would have been better if we didn't do things that way, but we'll have plenty of time as the release comes closer.
I'm still very jealous.
