TFW2005.com members Locustreign and Unitedbot have posted a response from the Hasbro UK Transformers Brand Manager regarding various Transformers items that should see, and in some cases will not see, a release on this shores with 2010.

The email states that the Transformers Revenge of the Fallen N.E.S.T. Scouts and Deluxes figures will be released and that Masterpiece Grimlock will be released in the 2nd half of the year as a Toys 'R Us exclusive.  The mail goes on to state that both the Transformers Revenge of the Fallen N.E.S.T. Voyagers-class and Transformers Animated Arcee and Autobot Ratchet Cybertron Mode will see not be released within the United Kingdom.

Now even though the email is from the current Transformers Brand Manager this is not a 100% confirmation that those toys will not be released.  In many instances in the past we have been told that figures would or would not be released within the UK which went on to be dis-proven.  This is often because the brand managers do not know specific names of items within assortments, that they simply make a mistake, or that things change over time and certain stores import the figures through US based partner companies such as Target or Walmart.  This is more likely to be the case for the NEST figures as Hasbro were pushing them hard pre the UK toy fair.
