Still a few too many known issues that would probably block this from being a viable RTM build, one or two more and then perhaps we might see a RTM if the plan is still for a public release in late April. (Well a non-insider full release of the RS2 update.)
I think the RTM version gives to insider 20 or 30 days before official release,if the official release is the 11 april then maby this is RTM and one more if on this version exist all language packs then i think is RTM.
