Tommaso Checchi joins Mojang to work on Minecraft Pocket Edition, already being asked when Realms will be live
Tom has already been asked thousands of questions about MCPE over Twitter today, most of which have to do with when Realms will be live (ugh). When asked what was coming for MCPE 0.7.3, he responded, "I've just barely compiled the code, so I don't know." He also responded to a follower, "it's my first time, still working on small tasks... I don't use to tweet a lot, I mostly reply and lurk but who knows!" So who knows, you might be able to get a response from Tom if you can't get one from us or Johan.
As a reminder, there are no confirmed features for MCPE 0.7.3 other than bug fixes. See the source link for Tom's Twitter.
