I've just bought Intuos 3 A3 tablet, and boy, I got to tell you, it's a beast ! I love that tablet and after 2 weeks of using I will never change it to anything else. I've heard there is no better tabled around.... oh, maybe except Axiotron's Mod Book Pro which is Mac Book Pro converted into tabled, but the price starts around $5k. Can you imagine? 5 thousand US dollars for a laptop which is your tablet? That's crazy! Anyway, guys at ModelMayhem.com found that probably (if the photos are real), Wacom's Intuos 4 tablet may be around the corner as it was found in one of the Future Shops. Here's the photo:
