Workflow tools for SharePoint

Will these still exist next year when SharePoint V3 is released with Office 2007?
The new inbuilt workflow will cover 80% to 90% of most business workflow needs along with Form Server. But these products provide efficiency right now which do server a purpose.
What is funny, is that one recent database job was all about tracking how long processes took so as to improve efficiency. It turned out to be workflow in disguise! So how many IT projects could be better served using workflow methodologies?
