Seems like the only way to get Guitar Hero news is by their community team messing up!
However the CandleBox DLC rumour is not a new one.
In May of this year an email was sent out from CandleBox which contained the following news update
We will also be readying ourselves for GUITAR HERO in June re-tracking Far Behind, You, Change, Cover Me & a few other gems from our debut release as well as tracking a few new CBOX #’s for our next release we’re hoping to have out to you by the end of this year. Keep checking in with us at CANDLEBOX ROCKS for all the pertinent info.”
Is the mentioning of CandleBox in the tweet today a surefire way of knowing that the DLC is on the way? We’ll have to wait and find out.
Oh yeah they posted it on facebook also.
