WOTC does very little wrong with products they acquire from other people or products based off those said aquisitions. For example, Magic was created by Richard Garfield. D&D bought from TSR. Pokemon imported from Japan, Avalon Hill (bought and tranformed into a family board game company). Everything else has been a good game that failed (netrunner, mechwarrior, star wars TCG, jyhad, etc) or a terrible or nitchy game to begin with (dreamblade, hecatomb, duelmasters, x-23, xena, hercules, everway rpg).
Wotc is also cursed with products they cancel to soon and products they attempt to take themselves into the electronic or mass media. D&D movie and its made for TV sequel, master tools, e-tools, dragon and dungeon online, gleemax, the D&D insider, the dragonlance movie, ployhedron, star wars insider, most support for the star wars rpg, duelist magazine (which must be why they made dragon and dungeon e-mags)...ironically the magic duelist info (i.e. mtg.com) is very good, comes out weekly, and is FREE.
The ONE exception to all of this is magiconline. That is the online e-product WOTC is handling well. If D&D were handle like magic is, we be golden.
Regardless, I think the print books for D&D 4e will be spectacular.
