Minolta at the time were ahead of the game with the wireless flash, albeit with some limitations at the time (ie no HSS, added later)
The problem was it did not get developed to the extent it should have thus other makers caught up and went a bit further.
I'm not really up to speed on the A77 as to where that stands for ratio flash with multiple units. As far as I can remember to do ratio you have to get a HVL-F58AM flash.
Obviously the disadvantage is that you have to buy the top end flashgun to do this. Where as this option is available even with a built in unit on older film bodies.
I don't know if the Minolta wireless was limited by the approach they had taken, or if they just felt it was good enough, but the other companies certainly did significantly improve on it. At the end of the film era, the big Minolta advantage was that it was standard at almost every camera level and used the built in flash as controller.
The new Sony wireless ratio using the 58 flash gun as controller is a significant improvement over Minolta ratio wireless (using the pop-up flash as controller) since the only Minolta ratio possible with the pop-up was 2:1 remote:popup. The 58 allows more groups. However, I really wish (unfortunately, I should trade mark those 3 words when I talk about Sony), that they had released (or would release) a wireless ratio controller similar to the old Minolta wireless, that had a small form factor like a compact flash, emitted an invisible IR signal but had the capability of ratio control as the 58 does. Without the 58 guide number flash tube and internals, it should be a lot less expensive, be much more portable, and not contribute any light to the exposure. But for some reason, Sony doesn't seem to get it.
