Inventory Manager 4.0 is also due out around the same time as WM 6.1 and will also be based on SMP 3.0.
Rounds 3.0 is currently targeted for a Q4 2014 update (as always dates are subject to change).
While I haven't tried it yet, deploying the other applications on to SMP 3.0 should involve a similar process to moveing WM 6.0 to SMP 3.
