The Beatles: Rock Band 2? Quite a possibility (IMO).

[Apples]

Yes there are good songs not yet released, but 45+ of them? I don't see it.

[HyeJinx1984]

We MAY get track packs, I highly doubt we'd get a sequel. Don't really need one.

Here's 36 right now that would work off the top of my head that aren't released currently, nor slated to be released in DLC. Not saying that this makes it anymore feasible, but just showing how diverse their career REALLY is:

Love Me Do
She Loves You
Please Please Me
All My Loving
Till There Was You
Please Mister Postman
Everybody's Trying to be my Baby
If I fell
And I Love Her
Anytime At all
Help!
You've Got to Hide Your Love Away
I've just seen a Face
Yesterday
I'm Down
We Can Work It out
Rain
I'm Only Sleeping
Good Day Sunshine
Doctor Robert
Got to Get you Into My Life
Strawberry Fields Forever
Penny Lane
Baby Your a Rich Man
Ob-la-Di-Ob-la-Da
Happiness is a Warm Gun
Blackbird
Rocky Raccoon
Revolution 1 (original version, not the single)
Lady Madonna
Hey Jude
Let it Be
Across The Universe
You know My Name (Look up the Number)
One after 909
The Long and Winding Road

I'd rather just get DLC.

[LuigiHann]

They could do exportable track packs based on albums, or sets of albums. But there's not really room or need for a second Beatles game on this generation of hardware. Maybe five years from now

[Grannd]

I don't see where there needs to be a Beatles 2 when DLC and on-disc Track packs will cover both those with and without an internet connection.

On the other hand, releasing TBRB2 in a year holding Help and Hey Jude exclusively, together with a DLC and TBRB1 import function would probably sell great too.
It could be a great profitmaker, but I think Harmonix will settle on DLC and most probably there will be track packs for those without an internet connection.

[DerTommissar]

Want to know if there would be a TB 2? Two words would answer that:

Third guitar.

If HMX could get that going, I'd bet they could eventually reboot this game. However, you'd either have to repurchase every song currently available, or play them with only 2 guitars.

If they could do that, they could easily redo a story mode with more venues and dreamscapes and so forth to pretty the game up further.

[Diyomaro]

I don't see The Beatles: Rock Band 2 happening honestly. MAYBE a track pack, but I see that as unlikely as well. They just need to pump out DLC. I wanna play Penny Lane, Hey Jude, and Help! already!!!

[JB392]

I would love\buy more DLC but for people without DLC maybe track packs could be a good idea.
