What's the ratios of the highest gear? The knowledge base says VX trannies have a .72 OD. Is this M5 going to lower hwy RPMs?
No worries, its not posted... until NOW :

Aisin AR5 Transmission
1st:3.75
2nd:2.26
3rd:1.37
4th:1.00
5th:0.73
R:3.67

4L30E
1st: 2.86
2nd: 1.62
3rd: 1.00
4th: 0.72
Rev.: 2.00

To answer your question, the OD is about the same but think about all the extra power you'll have going in reverse!
