Here is an updated
LINK to the WaveMaker Webinair
which has the Q&A part added at the bottom of the link, the video is the same as before. The Q&A, amongst other things, explains the difference between the Enterprise and Desktop versions.
It's interesting to note that unlike most community versions which tend to appear before the "paid for" version, in the case of WaveMaker new Enterprise versions will be released with the Community Desktop version being released about a Month later.
The Community Desktop version is free and Open Source, the Enterprise version which includes Cloud Space, Support and other benefits, costs $10,000 for 25 Containers or $100,000 for an unlimited number of Containers as outlined in the Q&A.
