Most likely it's nothing, but the past few days I noticed the guitar hero site has been down for maintenance: http://hub.guitarhero.com/ . It might of been down longer, but I don't frequent it much.
Normally I wouldn't think much of it, but a few things caught me off guard:
1) The logo. It's the original Guitar Hero logo.
2) It's not a typical 'site is down' error. It looks intentional, almost like it is preparing for something.
My apologizes if anyone posted this already. No matter how anyone feels about GH, having competition around helped innovate a lot of ideas. Hopefully this is a good sign.
