Rock Captain 99
Following the dreams!!
Riolu was also shown in the preview, just after Sobble and betore Beautifly!!i hate to be that guy but i wont believe its riolu till i see it until than its going to be sobble for me, i believe current starter>riolu in terms of marketing its been teased in the same page as riolu all the marketing for Lucario can easily be Korrina's, also we saw a sobble in the previews but no riolu why hide a pokemon he owns but not a "future pokemon" of his, and last point i will make is the magazine at first made me believe the color of the egg was similar to riolu a bit darker but seeing the preview the color of the blue seems more in line with sobble
