AM3+ is backward compatible with the AM3, but Bulldozer is for AM3+ only

It's easier (more reliable really) to overclock an x58 with 6GB in triple channel than a P55 with 8GB in dual channel.

I want more than 4GB of ram personally and 8GB at this point is overkill for me.

not really overkill, specially when you consider the nominal cost. Memory bandwidth is useful and I love having triple channel, but if anything P55 showed us that one less channel is not the problem. I applaud AMD, because flipping sockets every few years to test something that will have minute gains is what the server market is for. Besides unlike intel, they learned their lesson hard with the 939 to AM2 debacle.

how is that getting burned, if you buy an AM4 cpu it might be able to drop into an AM3+ board, but why would you ever expect that an AM3+ cpu can go into AM4 way before DDR4 is even out?

indeed, people keep forgetting this is AMD, not intel we are talking about. My AM2 may finally be dead but by god its socket had one hell of a lifespan.
