> My understanding is that the YubiKey Neo applet supports up to 2048 bit RSA.  Thus there are some keys that will work with the V2 SmartCard but not on the Neo.

Yes limitation is physical, the ship cannot have key size more than 2048 bit RSA on Yubikey, for the V2 SmartCard GnuPG, it's different, limitation was software (by GnuPG) but not hardware, so now it works with 4096 bit RSA.
