Um, they've been talking about a fourth movie for YEARS. Remember? They were supposedly going into space this time around?
I, luckily, haven't had to put up with war over which is better, cartoon or CGI, HOWEVER, I HAVE had to put with the war between canon shippers and mixed shippers before... I mean, REALLY, it got so ridiculous at times, which is why I don't ship any couple anymore (which is ironic, since I was actually the one who coined the name "Simanette" for Simon and Jeanette)... there are those who are so dedicated to the franchise as it is, that they will argue to the nines on why Brittany should only be with Alvin, Jeanette only be with Simon, and Eleanor only be with Theodore, then there are those who are so firm in mixing, that they'll argue just as loud and just as much as to why certain mixed pairings work better than canon. The interesting thing though is that the mixed couples come and go in popular phases... over the years, the "It" couples have been anything ranging from Simon and Brittany, Alvin and Eleanor, Dave and Vinny, even brotherly incest between Alvin and Simon, though perhaps the squickiest mixed couple to ever be a popular phase was Dave and Brittany.
