Personally, the Merchant in me would not allow the project to continue, had I been a Hasbro bean counter, especially after hearing things like scanning miniatures and recording sound bites for the online tool feature of then Master Tools software, while they have not completed the tabletop tool features. I also would fire the Wizards' project leader for shifting the Fluid developer's task to make MT an online game.
But the project still continued, under a different leadership (then Ryan Dancey) who has a pragmatic, business mindset and likes to get things done. He salvaged what he can from the project, set aside any online tool features and get back-to-basic (the original objective is to make an electronic aid to tabletop gaming), playtest it and tweak it, and sell the product at a low price, with expansions to follow.
After seeing what Fluid has done so far and with the promise of continued software support if Wizards should decide drop it in the future, I'm leaning toward getting e-Tools.
Fluid would also like to do business with other d20 publishers.
