As the roster stands right now (spots to be won in ST aside), do people think that the Cubs in 2008 will be legitimate World Series contenders?

Personally, I feel that they are in a slightly better boat than they were at the end of 2007. They've added depth to the pen and rotation. They've signed a legit RF and have been able to upgrade at C in house.

Could the current roster win the World Series? Sure, but I think a lot has to go right. There are a lot of 'ifs':

If Pie turns the corner
If Lilly doesn't regress
If Soto is as good as advertised
If Fukudome is as good as advertised
If Zambrano has a good year
If Hill has a good year
If Lieber is healthy
If Theriot gets better
If Cedeño turns the corner
If Soriano's leg problems don't come back

Personally, I think that Soto and Fukudome will be fine, and while I doubt Lilly will have a 2008 as good as 2007, I'm sure he'll be fine. But there are still some things that seem to be left up to fate.

I feel that our bullpen is great, our offense is fine, and our rotation is fine. And while I totally expect the 2008 Cubs to be good and make it to October, they don't seem, to me at least, to be a team that can dominate in the playoffs.

Do people feel differently? Do people think we need a new 2B whose name I won't mention since Al is sick of reading/hearing it. Do people think that we need a another top of the rotation Starting Pitcher?

I'm not meaning to start a debate about specific trades, although that would certainly be welcome. But simply how do people feel about the current roster and their chance at ending the streak in it's centennial year?
