I see it this way, why add this low priced instrument right at the time of retirement when previously nothing was offered in this very low (for Sadowsky) price range?
He's had a very successful shop and brand for a long time now, I'm sure he's made enough money to retire on. But he still wants to work, which is great, and if he wanted to, could continue on as he has done with his offerings.
Instead, we now we get the same lines, but now the Express will be 1K cheaper. A Sadowsky in this price range should sell very well with his reputation. I believe that Warwick may have insisted on an instrument in this price range otherwise it may not be worth their while to take over the operations where the previous point of entry was $1,900, they needed something that they can really sell, and this is it.
It's possible that money wasn't his primary motivation, but it should certainly be rolling in after the new Metro Express releases. My guess is that it could likely double the amount of total basses sold among all of his offerings.
