Today I saw two different strategies, and please note these are purely opinions, not facts, feel free to criticise
Microsofts announcements were more aimed at selling more xbox ones, particularly in europe
This was done by really bringing the big guns
Fifa - Cod - Halo MCC/5 beta - Quantum Break - Fable - AC:U - Tomb Raider
Fifa stuff was pretty pointless because we know of legends dlc, so we didnt see much new. But fifa is a great catalyst for european sales.
Mix in Cod with exclusive cod bundles, Sunset overdrive bundles, and you're fighting to have a good 2014 here.
On the other hand Sony didnt need to announce bundles or such, they have the one destiny white ps4, which they know (and we all pretty much know) is going to accelerate PS4 sales healthily on the week on destiny release. Add in the fact sony have sold 10million ps4's, and they are in a comfortable position. This comfortable position allows them to announce a bunch of games, particularly new ip's.
A lot of these aren't even for 2014, they are likely 2015 releases. Sony has destiny which will do well for them, and littlebigplanet which they hope will bring in the less hardcore audience i.e. the families, the kids and the core gamers.
I think, Sony think they have the rest of 2014 in the bag. The only real threat is Halo: MCC, but that isn't going to shift 5 million xbox ones, at most, maybe 1 or 2 million, at most (not necessarily on FW)
Sony are saving their big guns, the AAA titles that we gamers itch for for E3 2015. That is where we will see Uncharted 4, Santa Monica Studios, Media Molecules Play create share game and maybe even Sony Bend & Guerrilla games & Cambridge.
I say this because maybe half of those studios could easily announce their projects tomorrow, but the momentum is so strong with sony this year so far, and looks to be strong with the rest of the year. They need to challenge for 2015 where they know Microsoft will bring their big guns too.
2015 has the next AC, Evolve, Halo 5, Fable and now Tomb raider and many more. The action-type games for gamers. They will announce so much more at E3 '15 like Teasers of Gears of War.
A very indie and small game centric Sony and Microsoft Gamescom for 2014 just goes to say E3 is going to be awesome. It's where the true console war begins, all this now is just prep work.
The only difference is sony is in a comfortable position where they will sell well regardless, so can show the games like Rime, Wild, HellBlade. Games that aren't necessarily megatons so much as Tomb Raider, but add to a pile of games that can fill the lineup for spaces in 2015 between the huge games like batman and bloodbourne.
Microsoft on the other hand have to increase sales, and they need to do it soon. I can just imagine investors looking the weeks where PS4 is outselling xbox one 7:1 in europe or 2:1 in America and screaming at the lovely Phil Spencer, where words like Kando are being thrown around Sony CEI corporate offices with cheesy smiles.
Here's to a great 2015.
Post edit: Thanks for reading if you did. A couple of points, many new unannounced IP's were announced at sony's presser vs 1 at microsofts presser.
As a second point, to prove that this show was purely about accelerating sales, they did what us fanboys love to do, which is list games :)
Gta, Destiny etc. Whereas games like GTA, which will likely have marketing with PS, didnt even mention once.
