Guys, don't panic! Epic is doing a good job this time around.
A video release before March would be USELESS. Sure, it would boost the song back to the top 50 on iTunes, it would stay in the top 100 for 2 or 3 days and then, given the little airplay, it would fall back to the #130 - #150 range. They should release the video when the song is at least top 10 in one of its formats and that's what they'll do.
And of course she won't do TV promo. Labels are broke. Most artists only promote right before their album is released, no sooner. That being said, a lyric video and a radio tour when she comes back from Australia are an absolute MUST
