To me, no. My only concern when i decide to invest in something like a console is will it be successful enough to get support. The PS3 is and that's enough for me as an owner of the console.
Right now while I'm happy with all the 1st party announcements for Wii I'm probably more concerned so many 3rd parties still seem skittish about the system and how to make good games that exploit its unique HW.
I know it's OT, but by extension I'm also wondering how those same developers, who all apparently have great games cooking for Natal and the Wand, are going to deliver on the HD platform after apparently failing to get motion controls terribly well on the Wii?
Try to be reasonable... its easier than you think...
