Francisco Lomonaco,
O cartão xD tem um consórcio de empresas, visite este site aqui abaixo onde voce verá a lista de fabricantes para o cartao xD. Li que a Kodak esta começando a fabricar xD tb. O cartão da Olympus é fabricado pela Toshiba.
Somente o cartão da Olympus permite fotos "Panorama" Pese isto antes de comprar o seu cartao. Eu estou para comprar um cartão para minha Olympus D590 e vou comprar Olympus mesmo.

xD-Picture Card InformationMemory Card Market Memory card market for digital cameras is now growing at a remarkable pace with more than 30 percent annual growth. The driving force of the growth is nothing other than digital camera itself (with 30 - 70 percent annual growth). As a result of the wide range of application, memory cards are now used to various other products though still most people buy memory cards for their digital cameras.
Thus future memory cards should be designed primarily taking into account the users of digital camera.
Target of xD-Picture Card™ Semiconductor memory cards have such features that they are smaller, higher capacity and more reliable than floppy disc and other media. That's why they become applied to various digital products to store not only image data but also many different types of data including sound data and text data. The fact that memory cards "can store anything" = "become multipurpose" seemingly makes them convenient. But is it true?
Here are some problems:
●Digital camera usually can't recognize any data other than image data contained in the card. And a card previously used with other products cannot store many images when used with a digital camera. In such a case, you cannot see what data is contained in the card with the digital camera and may lose all the data stored by formatting the card. Or the valuable image data may be lost if the card is used with other products.
●When sound data is stored in a memory card, the data must be prevented from unauthorized copy to protect the copyright for the sound recordings. It requires a complicated unauthorized copy prevention system while, with respect to digital cameras, such a system is not necessary because it is the person who took the pictures that holds the copyright.
Thus a memory card exclusively for digital camera will make the price of the whole system as well as card itself lower, giving benefits to users.
What will be stored is the important property of users
It means that image data is one of a few data that a user of camera can create on his/her own (= he/she has the copyright) with the feature that it is the master copy. The answer chosen by licensor to allow the precious data, or the property of users, easily utilizable securing the high-reliability is "Memory Card Solely for Image Data."
