I wouldn't mind an e bike at some point. The new Trek Fuel EXE looks good but too expensive yet.If my next bike wasn't likely to be an ebike then I'd be considering a more trail oriented bike myself. I ride a commencal meta sx which is plenty and I do sometimes feel its too much bike for certain places. I do love it though. Just wouldn't mind a nice light thing again.
I think an e-bike plus a hardtail would be all that's needed.
