In 2007, "Pokémon Diamond and Pearl" were released. They take place in a new region called Sinnoh. They had 107 new Pokémon, which brought the total to 493. Another noticeable difference from the previous games was that "Diamond" and "Pearl" did not capitalize all the letters in names of Pokémon, people, towns, items, and other things that were important to the games. For example, Lugia would appear as "LUGIA" in previous games, but in "Diamond" and "Pearl" it would just say "Lugia." This cleared up a lot of players' confusion, because many thought that a sentence like "LUGIA is found in the WHIRL ISLANDS" looked unusual. A sequel to "Diamond" and "Pearl", "Pokémon Platinum" was released in the United States in March 2009. In May 2009 it was released in the UK.
