We all probaly know that Modern Day is most likely to be the last world, however when I read on the Modern Day page I found this pic I also find two texts 1. There is a possibility of this being the final world. However, Popcap has said on Facebook that Modern Day may not be the final world, as they mentioned that Dr. Zomboss has reinforcements that he can call from various time periods. and 2. This may also be referring to Modern Day part 2. This is most likely to be the second text as there is no silhouette after Modern Day (and we still are gonna get part 2 of Modern Day) but what are you thoughts? is Modern Day really the last world or are we gonna get more Extra worlds after it (which are not based on the story)
