Did Wendy's really change their sizes?

Wendy's has made many changes in the past year including adding more salads to their menu, offering healthier choices for combos, using a healthier oil, and now doing away with "Biggie" sized. But have they really done away with "Biggie" or just changed the name? I was at a Wendy's yesterday and ordered their new "Large" style combo. But to my surprise their "Large" is not a normal large, but their former "Biggie" size. Their "Medium" is your normal large-sized and their "Small" is actually your normal medium-sized. So it seems to me that in Wendy's effort to do away with "Biggie" to promote a more health conscious fast-food chain, they are actually tricking their customers into buying a bigger size. If they wanted to do away with "Biggie," why didn't they just do that? Their still paying the extra cost of keeping the "Biggie" size around, and if they would really do away with "Biggie" then maybe that extra money could be spent on healthier items to add to their menu selection.
