Yes same here. Still there are questions and doubts. First of all will He want to do it.
Second, will the engines allow the physics simulations like we have now.
Third. Is it worth time and money?
Forth. What if BikeSIM experience is better and GP Bikes would loose all community? As past past modders and maybe silent observers of the project they can copy the good ideas from GP Bikes and implement into much better game, which is finished.
Fifth. What is the future of GP bikes? Is it endless project, whats the point of constant development that might never end? Is there any plan for this project?
So many questions, still a lot of work. Game is great and is no doubt no one at this moment can match the simulation level of GP Bikes.
In answer to your questions quoted above(
just my opinions of course):
1: I doubt he will want to do it..... I suspect Pib is an old school indie-dev who likes to do everything himself? I suspect he will feel it's sacrilege to use anothers game/entertainment sdk to develop his projects, but I could be wrong.... I hope I'm wrong?
To me, using UE4 for development would be no different than using 3ds max or Maya to develop the 3D models used in Piboso's projects, but some indie devs seem to be living in the stone age still it seems?

2: Of course.... If you can programme it you can do it, no limits..... Might even be able to drop a lot of the current physics code into the engine and maybe more, but would take a lot of planning to do it and tie everything in with the additional capabilities of the UE4 engine. Might even be a good time to programme certain things better than he did previously? I suspect there are parts that Pib would programme differently if he had the chance?
3: I personally think so, especially if the community would be willing to buy again on release for the big improvements gained?
4: Yet to be known about BSE and wholly harder than people think to get this right(just look at Pibs signature to get the meaning of what I'm talking about).

5: Only pib can attempt to answer that one.
Again... Just my thoughts.
