I'd like to thank you all for the input. As it happens, it seems the last google update has completely changed the rankings for most of the EMD we were tracking. So either they really had crappy "other" optimization techniques, or google changes the importance of EMD.
Here's what I can take from this conversation:
1. EMD with good quality content and a descent back link will most probably rank higher then a domain without EMD in the domain name, but with similar/same content & backlink structure.
2. EMD with descent content and good backlink structure are probable a good place to have a link to the money site, but certainly not an option to replace the money site domain (which was never the intention)
Thank you all for your input.
