I guess its not just that the community edition is going away, it's that there isn't a way to buy outsystems lite. Something like a vmware type of 3 server starter pack??
It does depend on your strategy though, it seems like you are focusing on large enterprises, which is fine, but there are a whole lot of small to medium sized businesses that don't have developers on staff (or they are not full time developers) who would love to utilize the rapid development platform but are being priced out of it. I do a zillion different things from storage to virtualization to development. I like buying tools that increase my efficiency, for example one cool tool we use is Altova Mapforce. I can easily clear this purchase because its under the 10K threshold. If I go to my boss with a 30K all he does is laugh at me.
