Hi,
Yes, there is an update planned, if everything goes fine for next week. This isn't about xe3 support, because there is only a single line of 5.1 which won't run in XE3 (it is a firemonkey command that's not available anymore in FM2), but it is because we are finishing 5.5, with native printing, previewing, pdf and html exporting. We don't want to release a 5.2 today wiht xe3 support and another 5.5 a couple of days after that.
Please be patient, I think 5.5 is really worth it :)
Regards
Adrian.
