In reply to:

When the mk2 comes out, will I be able to use the upcoming software upgrades on my mk1 (with the unique mk2 features not working) or will there be seperate upgrades available each time?



The short answer is "the software works on both empegs". A somewhat more official answer is here (however, nothing on this BBS is REALLY official, but the statement is from one of the guys from empeg)...
