Watch our there, Amazon, Sony is prepping two new eBook readers and placing the Kindle series squarely in its sights — well, sort of. The duo of rumored Sony readers have yet to be made official by our favorite nose diving consumer electronics giant, but J&R reportedly outed the pair when it accidentally posted complete specs on each device to its site. Sony Insider caught the snafu before the pages were pulled and, well, you know how it goes. Neither reader really poses a direct threat to the Kindle 2 or the Kindle DX where capability is concerned — if the reported specs are on target, that is — but the PRS-300 pictured above in red will supposedly be available for $199 when it launches. An ultra-portable eBook reader with a 5-inch display for $100 less than the Kindle 2 could definitely be attractive to many potential buyers, especially if it goes on sale for the holiday season. Hit the jump for each readers’ specs.
