A little, but then I felt 360 was low on exclusives 2010 as well. Admitedly I have a gaming PC so for me the notorious 'console exclusive' don't count.
I don't think it matters too much right now, though. MS seem comfortable with the install base in US, UK, etc. and know that the 360 sees equal to superior software sales for multiplatform titles - their focus is clearly going to be Kinect and expanding the base with a smaller number of key titles for the hardcore (if I can use that term) namely a regular Halo title, Gears, Fable, Forza, etc.
With Mass Effect 2 heading to the PS3 due to EA aquisition, plus probably every future Bioware title now, and probably all future (and probably some past ones too) Valve games likely to head to PS3 as well, the number of exclusives heading to 360 is bound to shrink unless MS decides to sink a lot of money into comissioning third party exclusives - which I believe would be of little value to them right now in terms of growing the install base - butI think they'll let the current baseline continue 'as is' and look to add via Kinect and comissioning much less expensive titles for 360/Kinect vs expensive AAA HD titles.
I'll be very suprised if the PS3 doesn't see more exclusives due to its own development focus, and in fact for a while I've felt (excluding as I say the 360/PC titles which I get on PC and don't consider a true exclusive) the 360 has trailed PS3 for a while in the number of potentially promising exclusives - with Alan Wake really the only title of note for me in the last 12 months or more that I've felt interested in.
But like I say, I don't think this will actually harm the 360 at this point, particularly as it will see great sales of most FPS titles in US and will get more than enough multi-platform support to sustain it anyway.
