I would prefer that NEM and Nxt work together and that NEM becomes an asset riding on top of Nxt. Make Nxt the stock and NEM the currency.
Personally I'd build in 1% inflation per year as well into NEM, not into Nxt.. but that's another topic.
The tokens are only temporary.
I would rather wait for NEM's delivery. The process is pretty complicated for me and not sure it will work or not. As I have waited for a long time, it is acceptable for me to wait a few weeks.
