We finally get the name of a kaiju in the upcoming Godzilla movie, and it's the 8-legged Muto.
Details leaked through an action figure toy web site revealed details, which also mentioned a second kaiju.
UrbanCollector has yanked the item description, but the details are still available:

It's possible Muto could be an updated version of the spider-kaiju Kumonga (Spiega) from the 1967 Son of Godzilla movie.
However, another possibility would be the dead kaiju we saw in the leaked Godzilla trailer which more resembles a centipede/beetle of some sort:
Godzilla opens May 16, 2014 in 3D starring Aaron Taylor-Johnson, Ken Watanabe, Elizabeth Olsen, and Juliette Binoche, with David Strathairn and Bryan Cranston. The screenplay is by Max Borenstein, Frank Darabont, and Dave Callaham.
An epic rebirth to Toho’s iconic Godzilla, this spectacular adventure pits the world’s most famous monster against malevolent creatures who, bolstered by humanity’s scientific arrogance, threaten our very existence.
