You do not have to wait until v8.0 to get (many) of the Developer capabilities in Designer.
Designer v7.2 is scheduled to be FCS (First Customer Ship) in mid-December 2008 and will likely be GA (Generally Available) in first quarter 2009. You will need to upgrade to wM 7.1.2 if you want to use Designer 7.2.
Yes, it’s true that Designer 7.2 won’t have all of the capabilities in Developer but it will have many of the capabilities. Even though Designer 7.2 won’t have the OOTB ability to create a new wM Java Service from right-clicking the mouse button (like in Developer) you can still create wM Java Services in Designer (just like we have been doing in Eclipse for the past few years).
Designer 8.0 will have more capabilities…and so on, and so on… So stay tuned!
Mark: I have confirmed that you can do conditional mapping (and index mapping) on lines within a MAP step with Designer 7.2. (How do I know? Well, I’m currently using Designer 7.2 ). It seems pretty intuitive to me (no worse than Developer anyway )
