4.1 will be what was USB 1.1
4.2 will be what was USB 2.0
4.3.0 will be what was 3.0.
4.3.1GXY1 will be what was 3.2 1x1 (which was 3.1 Gen 1 (which was 3.0)
4.3.1GXY2 will be what was 3.2 2x1 (which was 3.1)
4.3.2GXY1 will be what was 3.2 2x2
4.4.0 will be double the speed of 4.3.2GXY1 (what was called 3.2 2x2) but will max out at 25mm (~1") cables and provide no power at all.
4.4.1 will be like 4.4.0 but will expand the length to 30cm (~1')
4.4.1ZORB22 will be like 4.4.1 but also carry up to 5W power for bus powered devices.
Go ahead and laugh, and then realise this isn't really that different than what we have now from USB-IF.
