They already said it in the news.
“The repositories that manage the servers, clients, graphic data, etc. for kTOS and iTOS are currently separate.”
“Lately, however, we’ve noticed a high demand for kTOS contents among iTOS players, and so we’ve decided to change our policy and work on merging the repositories for the two versions. So far, iTOS updates like new costumes and such were done through a partial application of contents, rather than a full-sized merging process. However, we feel that this repository merge is necessary to minimize patch gaps between both versions of TOS.”
This means that they will most likely do everything the same on both versions.
