Ozformers have posted their coverage from the 2010 Australian Toy Fair with the key points listed below:

First half of 2010 - red packed Movie line continues.
Second half of 2010 - yellow packed Movie line, red packed gimmick figures, Powercore Combiners, Generations, and Speed Stars. (August in America, Jun/Jul in Australia)

Mid year sees a big change in packaging styles for TFs and SW (their biggest two lines at the moment).
Animated - no more new figures to be released here. No Arcee or Ratchet either.
Human Alliance - still a Kmart exclusive here, and they are still committed to the line. But - only releasing 3 mid year and 3 at the end of the year, probably to make them look like a range/variety of figures, instead of one at a time.
Recon Ravage (the mailaway one) will be released here at ToysRUs next month.
MP Grimlock will also be a TRU exclusive here.
TF2 Robot Replicas definitly not being released here.
80% increase in sales for TFs during 2009 ($40mil - $23mil of that while the movie was in theatres), compared to 2008 ($17mil) and 2007 ($17mil).
