Just wait for 12 to be released, that shouldn't take too long anymore. We're in September now, I'd say 1-2 months waiting and it should be there. Also it seem like you're not really missing anything at all when not using 11.5. The forum(s) lack users being excited or even talking about the release, like they usually do. 11.5 only seems to have a couple of minor improvements, of which most, judgiung from the list should have been released in a free update version. I'd save some money if I were you and not buy this whole rip-off plan and wait for 12 to be release and upgrade then..... if 12 is really worth it at all.

Due to the childish TOS changes, I'm not allowed to link to my other products outside of Rendo anymore :(
