Or maybe not , it could be they already planned to release a new beta version of ThinApp in november. VMware announced this news at VMworld 2009. The final release is planned for Q1 2010 a little late if you ask me.. since there are already some working versions out there: for instance check Rubens video. 

Next to that i also found a nice howto that shows how to decompile Thinapp and Xenocode packages created by NickOn and a nice little script that executes Thinreg in a decent way with support for recursive folders (here).
