Sure, if Disney lets the comics stay in their niche market. But if Disney plans on taking over the comics distribution (now handled by Diamond... Disney has its own service) in order to make comics more accessible to the mass market, we may see, at the least, an increased attention paid to the Marvel Adventures line.
I'm not saying that Disney will "kidify" the comics, but I hope this move leads to Marvel's comics to be more... I dunno... heroic? Less hero-vs-hero and more Good vs. Evil. For decades Marvel was mature enough in their topics, but with heroes that were actually heroic (as an example, look at the Green Goblin cycle of Spiderman... you had some very dark themes there, culminating with the death of Gwen Stacy, and this was back in the 70s).
