Will there still be a Fat Controller?

So now it's to be Thomasina the Tank Engine?  In the interests of diversity - or political correctness, depending on your point of view -  The Rev. Awdry's creation is to be re-written for the 21st century,  introducing female and ethnic engines, and sending Thomas abroad to have adventures in foreign lands.  Even the Liverpudlian narration is to go - which of course raises the question - will it still really be Thomas the Tank Engine?
