Here are a few things I'd like to see:
- total library integration, including new DLC, old DLC, exports AND Beatles! (Plain and simple, if you make the Beatles exportable, you will go gold, maybe platinum within 12 months. Yes, I've heard it'll never happen, but it's still a valid suggestion to throw into Sir McCartney's inbox. I'll pay $19.99 for an export, as will others who shell out $50+ for COD each year, easy.
-proving the renewed and continued worth of the franchise (the community is airtight) to the record labels would be awesome: ie. tell Swan Song that they'll make a crap-load off of DLC and hungry Zep fans like Green Day did...see what happens.
- more hip-hop and pop to entice people who buy RB simply for it's ground-breaking vocals mode (far superior to the SD flakiness of SingStar). I don't care about the hip-hop-haters: the Snoop Dogg and Gorillaz tracks are popular and fun on karaoke, plus the newly remixed band parts make the old Snoop tracks feel fresh. Jungle Boogie by KATG was a blast too!
- magically bring back Hier Kommt Alex, Rock N Roll Superstar, Paranoid and Enter Sandman; all will rejoice in the nostalgia; lol
- actual " Lossless Audio/Hd Jukebox" option in the menus, so you can just kick back, relax and chill to HD master recordings on Blu-ray speakers without playing, failing, turing off sound effects, etc. etc.
- Harmonix needs to prove to the public why the pro modes (which were REALLY lacking in marketing; few people I know outside this community know RB3 actually came out, despite it representing the perfection of the rhythm genre craze; too bad, but fixable.
RB3 is definitely competitive to Rocksmith, the latter of which is beginning to amass a cult following, with its recent port to PC. However: the RB interface is copied, familiar and intuitive. I absolutely love the Pro Keys tutorial, and the ability to learn hundreds of new songs on piano. It's easy, plain-speak.
I know there are trollers out there who will immediately pounce all over the seemingly impossibly references to Zep, Beatles, etc...but I respond: The World is Yours, mang.
