Lots of good info from the write up, including the news that almost all of the effects will be practical, but I'll let the flavor of the article speak for itself:
Ultimately with any sequel what it comes down to is amping up the kills and the excitement while at the same time trying to make it at least as believable, if not more so, than the original. This is a task [director] Joe Lynch was more then up for, and his excitement about the materiel he’s directing served to make all the energy and high spirits on set down right infectious... everyone agreed that Wrong Turn 2 is shaping up to be a worthy follow-up to its predecessor and something that fans will get behind to show their support.
