sounds like a great deal to me and they are definitely authorized retailers so you should be all set. I can't say what they would do for a warranty, my guess is probably try to fix the one you send, they also might have a stockof refurbished v2s for that exact situation, but barring that I would assume you are correct, if you are under warranty and they can't fix or replace with the same thing they will probably upgrade you. Either way I wouldn't worry about it, delta 9 has excellent customer service and they will make it right for you should you ever have a problem
