It's not made by Codemasters. Codemasters contracted F1 2009 to Sumo Digital while they were busy with the HD versions (that ended up being 2010). Sumo Digital is also working on F1 2011 on the handheld versions.
Frankly, I enjoyed F1 2009 for what it is. Does it look as good as the console versions? Nope. Does it play like those versions? Nope. Does the save corrupt like on the console versions? Nope. That's more important for me.
