Harmonix' fremtid er om dagen uviss, men det skal ikke spillerne lide for. En rekke småfeil, uregelmessigheter og inkurier i Playstation 3-versjonen av Rock Band 3 har i dag blitt gredd med hårene, og det loves at det samme vil skje på Xbox 360 i nær fremtid. Flere oppdateringer utover dette vil også forekomme.

Her er en informativ, liten oversikt over hvilke feil som er fikset:

• Arena 12 Freeze (aka The Roadie Amp Loading Screen of Death) - If the amp loading vignette occurred immediately prior to an especially resource heavy venue it had the potential to cause a freeze. Your band should now be able to load their gear uninterrupted.

• Save Data Affected By Especially Long Band Names - Custom / Random Setlists specific to artists with especially long names (most notably Stevie Ray Vaughan and Double Trouble, Honest Bob and the Factory to Dealer Incentives, The Presidents of the United States of America, etc) that were not completed before playing through to the next auto save could result in corrupted save data.

• Iron Man Eyebrow Freeze in Character Creator - The Character Creator would sometimes seize up when reselecting the default eyebrow for the Iron Man pre set face. All eyebrows are now safe.

• Pause Scoring Exploit - To prevent abuse of repeated pausing mid-song to pad a score, we now disable score reporting on any song in which a player repeatedly pauses. Your crowd meter should go grey and you will not be able to complete any goals or achievements tied to score during that play through.
