Since they were already Apple hardware only apps, there is a good chance not much will change about it (at least in the near term) and they will just use it as a tool to increase the desirability of their hardware, just like they do for their iWork suite. I don't think it bodes well for the long term though, because Apple tend to not care much about stuff that don't make them a ton of money. It will probably become like their office apps, being updated at a glacial pace, used primarily as a marketing tool but never really reaching a level that would truly make them a worthwhile competitor.
