vntien,
Last I heard, JDE is supposed to end support of OneWorld XE on Feb. 28, 2005, so we are planning on upgrading next year. There is some valuable new functionality that we've been hearing about in ERP 9, such as Engineering Project Management, that is driving us toward ERP 9. However, even though ERP 9 is supposed to be released at the end of this month, we're going to wait until at least the first update/service pack comes out before we load it. ERP 9 is going to be a major upgrade, and I don't see any value to us in going to ERP 8 now, only to turn around within a year and upgrade to ERP 9; you'll need to weigh your need to upgrade with the cost of doing so and judge accordingly.
And I'm still waiting to hear how Peoplesoft will affect future product paths (e.g. their new roadmap).
