Before The E.N.D. came out, you could tell the BEPs were going in a more dance/electro direction because will.i.am was producing songs like Flo Rida - In the Ayer and Estelle - American Boy, and hanging out in clubs with David Guetta, so it was obvious he was heading to dance/electro. Now will.i.am's most recent single is Feelin' Myself, so maybe that's a sign of what's to come.
