Microsoft and Sony are not ones to stand back and let Nintendo take all the glory. Nintendo has already announced that the final version of the Wii U will be appearing at this years E3. Sony and Microsoft originally stated they would be waiting, at least another year, before they announce their new system. Rumor now has it that both Microsoft and Sony will be showing off  their next systems, during the E3 presentations. For me this makes E3 2012 that much more exciting. I love the air of competition and excitement when these companies battle it out.
