2009 JD's - any changes/news?

[KeithF]

Hi, I'm in the market for a JD zero turn mower - am looking at the Z445 and Z465.

Does any-one know if there are any changes due in 2009 for these models? Or any additions to this line?

When does Deere normally announce the next year's models?

Trying to decide whether to buy one now, or hold out for a few more months.

Thanks!
