I had NO idea wacom was planning to make intuos4, I tried to search it before ordered intuos3 6x11 but no result found until today. Too late I already have intuos3 6x11... bought it early this month, am still loving it! (I sold intuos3 A6 to my friend in 2007 and I missed it a lot, yep mistaken).
When I read intuos4 released today, took one minute feeling rejected for buying intuos3 wrong time when intuos4 just released 3 weeks later... However I had to be positive and believe intuos4 may be not good enough as intuos3 because intuos4 is a very new generation. intuos4 has new led built-in for the first time or new features (such as several buttons) on that tablet might be issue problems later. Then Wacom will produce intuos5 better, like CS3 to CS4 were not much to upgrade as they are both identical and tiny new extra features, hope you know what I mean. 🙂
