Ah, you're the greatest! Thank you! That made my night a little brighter - feeling so much more relieved now and genuinely, completely anticipating the film. :-)

(Also, the more I consider it, it makes sense for Phineas and Ferb to remain animated. If they do visit the third dimension - our world -, why would they themselves change? It wouldn't fit with what we've already seen regarding dimensions.)
