Helping people who are only generally/vaguely familiar with digital backs learn about the range of options they have, and the pros, cons, and costs of each is literally most of my job. I do it every day and would be glad to help. Feel free to shoot me an email or call.
There is a decent chance you can do something useful with your existing back with the right software and/or accessories. It can also be used as a trade-in towards a newer back.
You can find some good information (and some bad information - it is the internet after all) in the past forum posts here and on getdpi.com, and also meet other photographers in your area that shoot medium format. Most are pretty friendly folks more than happy to share their experiences and opinions.
If you want more specific advice on this thread I suggest you give us as much information as possible about what your needs and wants are, and your general budget range. Information like what kinds of things you shoot, what cameras you use now and what you love and hate about those cameras, what your level of experience is in Lightroom, Capture One, and Phocus, and what your technical needs are (do you need higher ISO? do you need fast shooting? do you need long exposures? etc).
It can feel a bit overwhelming, but it's really not. There are few bad options, as long as you have some reasonable budget (medium format can be very hard and limiting at the very low end). As one example the very modern Credo 40 (USB3/FW800/retina-touch-screen/dalsa sensor) is on promo right now starting at $12,995 (
Credo 40 promo). I don't think that kit is right for you since you already have an H platform to take advantage of, but it's a good example of the very capable systems you can get nowadays at the 10-20k price point (there are also, obviously very very good options at the 30-40k price point but my point is you don't have to get that high before the systems are really very good).
