June could be a hot month for 10-inch tablets if a recently leaked document from "a major U.S. retailer" containing release dates and prices turns out to be true. The document, dditionally, HP has a 7-inch webOS tablet (codenamed Opal) in the works with a planned release in September. Needless to say, you should take all this with a grain of salt, as delays are all-too-common in the industry and some of these products haven't even been officially announced.
