To yachtman's point, that's not a spec sheet, not a full one anyway. Those may be important details, but that's far from a complete picture of the final device. No mention of the specific processor, amount of RAM, type of graphics, that's really just a very bare list of features they've given, and, as the article indicates, there is no mention of the form of connectivity involved. I don't know whether the design is finished yet or not, but it would seem to me they still have a little time to add 3G or 4G if they want.
I expect that any delay in 3G or 4G options will have more to do with them trying to pick a carrier and work out the pricing on that end. MSFT hasn't been in this business before, so they don't have a norm to jump to, so they have to be careful, although the idea of selling a non 3G or 4G model only to sell one that has it a little later would probably be a bad idea.
