well, the new E is coming in soon, around early to mid september at least according to some sites in the UK, not sure about the US, would assume a similar timeframe.
the old S is being discounted in the states which probably signals a new model is coming, either possibly being shown off at IFA or just being introduced in mid august like last years was. If anything shows up at IFA perhaps it will be a concept using android that could replace the X or just a new S series, which could be just the japanese S series with no atrac support. If anything, news will come in mid august to late august for other additional models.
I should mention the new E series in the US also has a USB-port like the previous E in the states, so no WM-port.
