Forget about Amazon UK's variable estimations, Sony's gone ahead and given us official release details for its OLED-equipped NWZ-X1000 series Walkman -- known there without the "Z" but with an one-seg TV tuner. Street date is April 25 and the open price is 40,000 yen (US $400) for the 16GB NWZ-X1050 and 50,000 yen for the 32GB NWZ-X1060. Both models will be availble in black or red. No word yet on US or Europe date, but we can't imagine those will be far behind.[Via
