I don't have one (yet?) but if I had to choose where to put my money it would be on SONY and a PS4.
1.) Bluntly, FUCK MICROSOFT Xeverything! I have no confidence in them. Not because I'm a fan boy of one or the other, I've been fortunate enough to have both [XB/PS2, 360/PS3], but because the 360 is an abomination. Their persons in charge, consoles, peripherals and the way they conduct business are garbage and in no way benefit a customer. (Releasing a console they knew would break, racing wheel that sets on fire, THE WORST D-pad ever made in the history of gaming, camera that when plugged in reaches unsafe temperatures, HDDVD, don't move the console when playing a game if you don't want the game disc totally ruined, etc...)
2.) Just recently one of the morons in charge stated that they are working on having a larger influence in the PC gaming market. Trying to figure out how to copy Steam basically. Think about that for a second... Microsoft wanting to get in on the PC gaming market. The same fucking assholes who's operating system is on billions of PCs just now decide to beef up their PC presance. They have no fucking idea what they are doing. 0%
3.) Most XBONE games are coming out running at lover resolutions than the PS4. Argue who's better all you want. I'm used to playing games on PC so I prefer to play in 1080p not 920 upscaled. "Next-gen" . (Ribbing a friend last night over buying Watch Dogs for XBONE when his PC would crush it. He said it looks worse than GTAV on PS3 at times. I value his opinion(s).)
If you don't care about exclusives you should build a gaming PC and cock a snook at console gaming.
