Updated from 10:25 a.m. EST to provide additional analyst comments regarding Android in the thirteenth paragraph.NEW YORK ( TheStreet) -- Amazon ( AMZN) is being officially put on notice, as Barnes & Noble ( BKS) announced not one, but two, new NOOK tablets; the NOOK HD and NOOK HD+. Barnes & Noble is clearly going after Amazon with the two releases, which are comparably priced to the new Kindle Fire HD tablets. The new 7-inch NOOK will sell for $199, and the 9-inch tablet will go for $269. The 7-inch version of Amazon's Kindle Fire HD starts at $199, while the 8.9-inch model starts at $299.

Initially NOOK Video will include content from HBO, Sony ( SNE), STARZ, Viacom ( VIA), Warner Brothers and Walt Disney ( DIS). The NOOK HD has a screen resolution of 1440 x 900, with 243 pixels per inch (ppi), better than the 7-inch Kindle Fire HD, which has 216 pixels. The press release even takes a shot at Amazon, saying "
