Just to "pile on", I was told the same thing both by the CS rep handling my RMA replacement and in chat. They claimed that they were out of stock on new gimbals (I doubt that) and replacements. They indicated they were waiting on more to be manufactured. They also indicated I was getting a new gimbal unit, and didn't indicate either way on the Solo vehicle, which leads me to believe it's a reconditioned unit.
It's standard practice for companies to do this, though I think it sucks for a unit that crashed in just over 1 month of ownership to get less than the new vehicle I had... but one can argue "like new" condition. But it's also standard practice for most companies to issue reconditioned stock first for replacements, and move on to regular stock should an issue like "shortage" arise. That's why their replacement/warranty documentation usually indicates *may* be replaced with reconditioned units or similar language.
Where I think 3DR is really failing here is Customer Service. I've been without mine for a month... just over actually. I'm close to being without it as long as I had it. I'm missing the awesome time-lapse of my house being built that I was working on and all that goes with not having it. But in the end, all of these types of customer stories should have 3DR taking action on that massive amounts of stock they are supposedly sitting on. Take care of your claims with stock until reconditioned units are available. We shouldn't be waiting this long, even if they are unique in this replacement program. It's not very customer-centric.
