I wouldn't say MUST. Context plays a big role in that post If you go back to that original post you see that someone was confused and thought that the new game was plant tycoon. It is very possibleall that post was meant to be was clarify. I'm not saying that it can't be a new game but Lady never said it wasn't a sequel. It looks like from that preview shot that it's a sequel. I would like it to be vv4 personally. I think a sequel to PT or FT wouldn't be all that fun and i probably wouldn't buy it.
