They will have all of the various flavours fitted as you say it's only a chipset. I suspect all GPS boxes will have all of them. Why not? recieving the low Res signal is free. If one drops out you can use another one. You have 3 sets of data available so you can pick up a fix quicker.
The US it is illegal to receive anything other than GPS. If you have hardware which is not officially US import model it will likely receive all of them. If you root your device you can also remove the restriction. If you blow a new os onto an android device such as Cyanogen you can also get round it.
They have no real way of knowing what you are recieving. But it stops people marketing services utilising the other systems.
But we shall see what the political choice is if the project continues to be funded or not. Loads more cash needs to be spent to get the full functionality and the market for the commercial product has pretty much evaporated. Thanks to dgps becoming more economic and mainstream and sbas being rolled out through Europe. Anyone that needs accuracy can already do it with a brief case of kit. Or a single box that can receive sbas.
Personally I don't think it will survive but we shall see. The financial side of things is going to get interesting.
