I was talking to a Verizon associate at one of those mall booths about a week ago, asking the same question. It was comical what I heard from this guy. He basically was unaware of WP7...completely oblivious to it. He was equating it to Windows Mobile and said they already had if the last 2 years. I tried to insert a "but" but I couldn't politely help him to know what WP7 is. So I nodded my head just long enough to make a dignified break away from the conversation and carry on about my business, never to ask that question again of a Verizon associate...lol.
I had a similar experience. First, I'd filled out a Verizon customer service questionnaire, and complained about WP7 not being out. Then a manager of a corporate store called me, took down my complaint, I told him dates of when the MS offer expired each time it was updated, and told him that I'd switched to Sprint because I wanted WP7 but was forced to switch back because I couldn't have a conversation without dropping the call. He said I may hear back from a district manager (I let him know that my issue isn't with a store, but corporate).
A week or two later, I was out and about, stopped at a non-corporate store, as it was the day that the latest rumor said the phone would be out. I asked about WP7, and one associate said "we don't have Windows Phones." I said, yes, you do - here's my Verizon Touch Pro 2 - but I want Windows Phone 7. They told me they aren't going to have one. I told them of the Trophy, and one associate went to look it up, and he said he didn't see it on "coming soon" so he's not sure what it is. I couldn't believe it. I would expect that the people selling the phones would know as much as I could find on the internet, but alas, I guess my expectations are too high.
I know it's no consolation given that we have no idea when it will come out on Verizon, but if it makes a difference to you, it looks like there will at least be a choice between two phones, not just the Trophy. Latest rumor says that HTC Pro7 is coming to VZW, but doesn't say when:
