The EA Forums (thanks Ant and Voodoo Extreme) have word that the possibility of another patch for Need for Speed: Most Wanted has gotten the thumbs-down from the brass at EA:

Final result - there will not be another patch for Most Wanted.

Longer version - While I'm sure very few of you are surprised by this, there was a good deal of internal debate surrounding this patch and whether to proceed. While there was never a question of whether there should be support for the community, the issues were a matter of time and resources. Both of which were not available.

The positive however, is that all the information collected on this issue won't be tossed aside and will be used for any future releases.

So with that, I can only add that I'm sorry I couldn't do more.
