I'm not a fan of them splitting the seasons either. It's just gonna prolong the end that we all want to see, and it'll make it feel like two different seasons in a way. They may even release them in two different DVD/Bluray box sets (like they did with the Sopranos.)
However, the good part of it is that the show will come back on the air sooner if they split the season up since they only have eight episodes to write and film at a time. Otherwise, they wouldn't bring the show back until all sixteen were completed.
